              CONSENT SOLICITATION STATEMENT OF THE STOCKHOLDERS'
          COMMITTEE FOR NEW MANAGEMENT OF TESORO PETROLEUM CORPORATION
    
 
To the Stockholders of Tesoro Petroleum Corporation:
 
     The time has come for the stockholders of Tesoro Petroleum Corporation, a
Delaware corporation (the 'Company'), to take charge of the future of their
investments in the Company. Toward that end, a group of concerned stockholders
has formed The Stockholders' Committee for New Management of Tesoro Petroleum
Corporation (the 'Committee') in order to solicit consents from the holders of
common stock, par value $0.16 2/3 per share (the 'Common Stock'), of the Company
to take action without a stockholders' meeting, as permitted by Delaware law.
 
     The Committee is soliciting consents with respect to:
 
     1. The amendment of Sections 2.1, 2.2 and 2.7 of Article II of the By-Laws
of the Company to:
 
          (a) set the number of directors that constitute the Board of Directors
              of the Company (the 'Board') at five;
 
          (b) unambiguously provide that stockholders may remove any or all
              directors, with or without cause, whether at an annual or special
              meeting or by written consent;
 
          (c) provide that vacancies created on the Board by the removal of one
              or more directors be filled only by stockholder action; and
 
          (d) repeal any and all By-Law provisions or amendments thereto adopted
              after November 14, 1995;
 
     2. The removal of all seven of the present members of the Board and any
person or persons elected or appointed to the Board prior to the effective date
of the proposed actions set forth herein; and
 
   
     3. The election of George F. Baker, Gale L. Galloway, Alan J. Kaufman,
M.D., James H. Stone and Douglas B. Thompson as directors of the Company
(collectively, the 'Committee Nominees'), to serve until their successors are
elected and qualified.
    
 
   
     On February 5, 1996, pursuant to Section 213(b) of the Delaware General
Corporation Law (the 'DGCL') and in accordance with the By-Laws of the Company
as believed to be currently in effect (the 'By-Laws'), the Committee requested
by written notice delivered to the Secretary of the Company that the Board fix a
record date for this consent solicitation. On February 15, 1996, the Company
announced that the Board had set February 24, 1996, as the record date for the
purposes of this solicitation (the 'Record Date'). This Consent Statement and
the related WHITE Consent Card are first being sent or given on or about

February 29, 1996, to holders of record of Common Stock on the Record Date.
    
 
     YOU ARE URGED TO CONSENT TO THE REMOVAL OF THE BOARD AND THE ELECTION OF
THE COMMITTEE NOMINEES BY MARKING, SIGNING, DATING, AND RETURNING PROMPTLY THE
ENCLOSED WHITE CONSENT CARD IN THE POSTAGE-PAID ENVELOPE PROVIDED. FAILURE TO
EXECUTE A CONSENT WILL HAVE THE SAME EFFECT AS WITHHOLDING A CONSENT. SEE 'THE
CONSENT PROCEDURE--SPECIAL INSTRUCTIONS.'
 
     THE COMMITTEE URGES YOU NOT TO SIGN ANY GREEN REVOCATION OF CONSENT CARDS
SENT TO YOU BY THE COMPANY. IF YOU HAVE PREVIOUSLY SIGNED AND RETURNED A GREEN
REVOCATION OF CONSENT CARD, YOU HAVE EVERY REASON TO CHANGE YOUR MIND AND MAY DO
SO BY MARKING, SIGNING, DATING AND RETURNING A LATER-DATED WHITE CONSENT CARD.
 
     If your shares of Common Stock are held in the name of a brokerage firm,
bank nominee or other institution, only it can execute a Consent Card with
respect to your shares. Accordingly, please contact the person responsible for
your account and give instructions for a WHITE Consent Card to be signed
representing your shares. The Committee requests that you confirm your
instructions to the person responsible for your account in writing and provide a
copy of such instructions to the Committee, c/o Morrow & Co., Inc., 909 Third
Avenue, New York, New York 10022, so that the Committee will be aware of all
instructions given and can attempt to ensure that such instructions are
followed.
<PAGE>
   
     THE PROPOSED ACTIONS WILL BECOME EFFECTIVE AT THE TIME THAT WRITTEN
UNREVOKED CONSENTS OF THE HOLDERS OF A MAJORITY OF THE SHARES OF COMMON STOCK
OUTSTANDING AT THE CLOSE OF BUSINESS ON THE RECORD DATE ARE DELIVERED TO THE
COMPANY, PROVIDED THAT THE REQUISITE CONSENTS ARE SO DELIVERED WITHIN 60 DAYS OF
THE EARLIEST DATED CONSENT SO DELIVERED TO THE COMPANY (THE 'EFFECTIVE TIME').
AS OF THE DATE HEREOF, NO CONSENTS HAVE BEEN DELIVERED BY THE COMMITTEE TO THE
COMPANY. ACCORDINGLY, THE 60-DAY PERIOD HAS NOT COMMENCED.
    
 
     If you have any questions about completing or signing the WHITE Consent
Card or require assistance, including assistance in assuring that any of your
shares held by brokers or other nominees are voted, please call Morrow & Co.,
Inc. at (800) 634-4458.
 
                      REASONS FOR THE CONSENT SOLICITATION
 
     The Committee is soliciting the consent of holders of the Common Stock to
actions that would result in the removal of all incumbent members of the Board
and their replacement with the Committee Nominees, who will devote their
energies to reorganizing and revitalizing the Company.
 
     THE BASIC ISSUE WE ARE RAISING THROUGH THIS CONSENT SOLICITATION IS WHETHER
THE INCUMBENT DIRECTORS' RECORD JUSTIFIES THEIR CONTINUATION IN OFFICE OR
WHETHER A NEW BOARD OF DIRECTORS SHOULD BE GIVEN THE OPPORTUNITY TO SEEK NEW
DIRECTIONS FOR THE BENEFIT OF ALL STOCKHOLDERS OF THE COMPANY.
 
     In our view the answer is clear: We think that the Company's current
management has failed to perform its primary function--maximizing stockholder

value.
 
     WE THINK THAT MANAGEMENT WILL CONTINUE WITH BUSINESS AS USUAL FOR THE
FORESEEABLE FUTURE UNLESS STOCKHOLDERS ELECT A NEW BOARD.
 
     We believe that many of you share our discontent and concerns. In order to
address those concerns, the Committee seeks your help to remove the directors
now in office and elect five new directors who, we believe, will be responsive
to stockholders and firmly committed to the goal of increasing stockholder
value.
 
     Your consent is important. No matter how many or how few shares you own,
please help us to improve stockholder value by completing, signing, dating and
mailing the enclosed WHITE Consent Card promptly. The Committee urges you not to
sign any green revocation of consent cards sent to you by the Company. If you
have previously signed and returned a green revocation of consent card, you have
every reason to change your mind and may do so by marking, signing, dating and
returning a later-dated WHITE Consent Card.
 
                         THE COMMITTEE AND ITS NOMINEES

                           THE COMMITTEE'S PROPOSALS
 
     The Committee believes that a new Board must be elected in order to further
stockholder interests. To achieve that end, the Committee is requesting
stockholders to give their written consents to the following actions:
 
1. BY-LAW AMENDMENTS.
 
     The Committee is proposing amendments (the 'By-Law Amendments') to certain
provisions of the Company's By-Laws. Our first proposal concerning the By-Laws
relates to the size of the Board, the removal of directors and the filling of
vacancies on the Board. The purpose and effect of each of the Committee's
proposed By-Law Amendments is to facilitate the proposed removal and replacement
of all incumbent directors, as discussed further below.
 
     Article II, Section 2.1 of the By-Laws, as now in effect, provides that the
number of directors who constitute the whole Board is to be determined by
resolution of the Board, but may not be less than three. The Committee believes
that the entire Board currently consists of seven directors. The Committee's
proposed amendment to Article II, Section 2.1, if adopted, will fix the number
of directors at five, while maintaining the authority of the Board to increase
or decrease the number of directors. The proposed amendment is designed to
ensure that the Committee Nominees, if elected, will maintain majority
representation on the Board in order to carry out their plan of seeking to
maximize stockholder value.
 
     Under the General Corporation Law of the State of Delaware (the 'DGCL'),
directors of a corporation without a classified board and whose certificate of
incorporation does not otherwise provide may be removed with or without cause by
the holders of a majority of the outstanding shares entitled to vote in the
election of directors. The Company does not have a classified board, and its
Certificate of Incorporation makes no provision respecting the removal of
directors. In addition, unless a Delaware corporation's certificate of

incorporation otherwise provides, the DGCL permits stockholders to take action
without a meeting and without prior notice if a consent or consents in writing,
setting forth the action so taken, are signed by the holders of outstanding
stock having not less than the minimum number of votes that would be necessary
to take such action at a meeting at which all shares entitled to vote on that
action were present. Under the applicable provision of the DGCL, stockholder
action by written consent is effective when written consents from the holders of
record of the minimum number of shares of stock necessary to authorize the
action are executed and delivered to the corporation within 60 days of the
earliest dated consent so delivered.
 
     Since the DGCL provides that the directors of a corporation may be removed
without cause unless otherwise provided in the certificate of incorporation, and
because the Company's Certificate of Incorporation contains no contrary
provision, we believe that one of the fundamental charter rights of the
Company's stockholders is to exercise complete and unfettered discretion in
choosing and changing the persons who manage its business and affairs. Section
2.7 of Article II of the By-Laws provides that directors may be removed (with or
without cause) at a special meeting of stockholders called for that specific
purpose. Other provisions of the By-Laws, however, state that stockholder
actions which may be taken at special meetings may be taken by written consent
in lieu of a special meeting, subject to certain requirements. The Committee
believes, therefore, that the By-Laws (as well as applicable provisions of the
DGCL) permit the removal of directors without cause through use of a written
consent solicitation like the one in which the Committee currently is engaged
and do not limit the exercise of the removal power to special meetings. In order
to achieve certainty, however, the Committee's Consent Card includes a proposal
to amend Article II, Section 2.7 of the By-Laws to provide unambiguously that
stockholders may remove any or all directors with or without cause, whether at
an annual or special meeting or by written consent. The adoption of this
amendment will facilitate the removal of all of the incumbent members of the
Board, as discussed below.
 
     Sections 2.2 and 2.7 of Article II of the By-Laws provide that vacancies
created by the removal of a director may be filled by the majority vote of the
remaining directors. These provisions permit such vacancies to be filled without
any stockholder participation. The Committee proposes to amend Article II,
Sections 2.2 and 2.7 of the By-Laws to require that such vacancies be filled
only by stockholder action. This proposed amendment is intended to prevent the
incumbent Board of Directors from filling any of the vacancies which would be
created upon the removal of any of its members.
 
                                       4
<PAGE>
   
     The text of Sections 2.1, 2.2 and 2.7 of Article II of the By-Laws, as
believed to be currently in effect, and as proposed to be amended, is set forth
in Appendix II attached to this Consent Solicitation Statement.
    
 
     On November 14, 1995, the Company filed with the Securities and Exchange
Commission (the 'Commission') its report on Form 10-Q for the quarter ended
September 30, 1995 (the '1995 Third Quarter 10-Q'). The 1995 Third Quarter 10-Q
included as an exhibit a form of By-Laws for the Company which indicated that

they reflected amendments made by the incumbent Board on September 27, 1995.
Those amendments include (i) a new requirement of 60 or 90 days' prior notice in
order for stockholders to nominate directors or place matters on the agenda at
an annual or special meeting of stockholders and (ii) new requirements for and
conditions upon actions by stockholders by written consent. In the Committee's
view, the effect of these and other By-Law changes made by the incumbent Board
is to increase the difficulty, time and expense of actions by stockholders to
exercise their rights effectively as the Company's true owners.
 
     Additionally, the By-Law Amendments we are proposing include the repeal of
each provision of the Company's By-Laws or any amendment thereto adopted by the
incumbent Board after November 14, 1995, and prior to the Effective Time. The
reason for this proposed repeal is to address the possibility that the Board may
have taken, and not yet publicly disclosed, actions that the Committee might be
opposed to or that the Board might take during the pendency of this
solicitation. The Committee, however, is not aware of the adoption by the
incumbent Board after November 14, 1995, of any provision of the Company's
By-Laws or any amendment thereto, and the Committee has no reason to believe at
this time that the incumbent Board has adopted any such provisions or amendments
that have not been disclosed. In the event that the Committee becomes aware of
any action taken by the incumbent Board to amend the By-Laws following the date
of this Consent Solicitation Statement, the Committee will distribute as
necessary additional materials describing the By-Law provisions or amendments
that would be affected by the By-Law repeal amendment. Additionally, if the
By-Law Amendments are adopted pursuant to this consent solicitation, prompt
notice, including a description of such repealed By-Law provisions or
amendments, must be given by the Company pursuant to Section 228(d) of the DGCL
to stockholders who did not execute consents. Moreover, if the By-Law Amendments
are adopted pursuant to this consent solicitation, a description of such
repealed By-Law provisions or amendments will be included in the report on Form
10-Q for the quarter in which the Effective Time occurs.
 
     As indicated above, the 1995 Third Quarter 10-Q includes the By-Laws as an
exhibit. Accordingly, the Committee assumes that the By-Laws, in the form filed
with the 1995 Third Quarter 10-Q, were current as of November 14, 1995, the date
of filing, and the Committee's proposed By-Law Amendments would not repeal any
provision of the By-Laws that was publicly disclosed prior to that date, other
than as specifically described herein; however, any amendment to the By-Laws
adopted by the Board since November 14, 1995 and prior to the Effective Time
would be repealed. There are no provisions in the By-Laws or in the Company's
Certificate of Incorporation restricting the ability of stockholders to amend or
repeal provisions of the By-Laws without the consent of the Board. Although, to
the Committee's knowledge, there is no Delaware precedent precisely on point,
the Committee is confident that such proposed repeal of undisclosed By-Laws or
amendments is enforceable. If it were not, By-Laws adopted by the Board would
not be automatically repealed, but would be subject to challenge in court.
 
     THE COMMITTEE RECOMMENDS THAT YOU EXECUTE THE ACCOMPANYING WHITE CONSENT
CARD FOR THE PROPOSED BY-LAW AMENDMENTS.
 
2. REMOVAL OF ALL INCUMBENT DIRECTORS.
 
     Based on the Company's filings with the Commission, the individuals who now
sit on the Board are Robert J. Caverly, Peter M. Detwiler, Steven H. Grapstein,

Raymond K. Mason, Sr., John J. McKetta, Jr., Bruce A. Smith and Murray L.
Weidenbaum. The Committee believes that the incumbent directors have failed to
maximize stockholder value and should be removed and replaced with the Committee
Nominees. ACCORDINGLY, THE COMMITTEE RECOMMENDS THAT YOU EXECUTE THE
ACCOMPANYING WHITE CONSENT CARD FOR REMOVAL OF ALL OF THE PRESENT MEMBERS OF THE
COMPANY'S BOARD AND ANY PERSON ELECTED BY THE INCUMBENT DIRECTORS (WHETHER
BEFORE OR AFTER THE DATE OF THIS CONSENT SOLICITATION STATEMENT) TO FILL ANY
VACANCY OR NEWLY CREATED DIRECTORSHIP.
 
                                       5
<PAGE>
3. PROPOSED ELECTION OF THE COMMITTEE NOMINEES.
 
     If the proposed By-Law Amendments are adopted and the Company's incumbent
directors are removed, the entire Board will consist of five directorships, all
of which will be vacant. To fill those vacancies, the Committee proposes the
election of the Committee Nominees--George F. Baker, Gale L. Galloway, Alan J.
Kaufman, M.D., James H. Stone and Douglas B. Thompson. Certain information
concerning the Committee's Nominees is set forth above under the caption 'THE
COMMITTEE AND ITS NOMINEES' and in Appendix I attached to this Consent
Solicitation Statement. Each of the Committee Nominees has agreed to serve as a
director of the Company, if elected.
 
     THE COMMITTEE RECOMMENDS THAT YOU EXECUTE THE ACCOMPANYING WHITE CONSENT
CARD FOR THE ELECTION OF THE COMMITTEE NOMINEES TO THE BOARD. THE COMMITTEE
URGES YOU NOT TO SIGN ANY GREEN REVOCATION OF CONSENT CARDS SENT TO YOU BY THE
COMPANY. IF YOU HAVE PREVIOUSLY SIGNED A GREEN REVOCATION OF CONSENT CARD, YOU
HAVE EVERY REASON TO CHANGE YOUR MIND AND MAY DO SO BY MARKING, SIGNING, DATING
AND RETURNING A LATER-DATED WHITE CONSENT CARD.
 
                               CONSENT PROCEDURE
 
     Section 228 of the DGCL states that, unless otherwise provided in the
certificate of incorporation of a Delaware corporation, any action that is
required to be or may be taken at any annual or special meeting of stockholders
of that corporation may be taken without a meeting, without prior notice and
without a vote, if a consent or consents in writing, setting forth the action so
taken, are signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted, and those consents are delivered to the corporation by delivery to its
registered office in Delaware, its principal place of business or an officer or
agent of the corporation having custody of the books in which proceedings of
meetings of stockholders are recorded. The Company's certificate of
incorporation does not prohibit stockholder action by written consent.
 
   
     Section 213(b) of the DGCL provides that if no record date has been fixed
by the board of directors, the record date for determining stockholders entitled
to consent to corporate action in writing without a meeting, when no prior
action by the board of directors is required, will be the first date on which a
signed written consent setting forth the action taken or proposed to be taken is
delivered to the corporation by delivery to its registered office in Delaware,
its principal place of business or an officer or agent of the corporation having

custody of the books in which proceedings of meetings of the stockholders are
recorded. On September 27, 1995, the Board, without stockholder involvement,
amended its By-Laws to provide that a stockholder seeking to have the
stockholders of the Company authorize or take corporate action by written
consent is required to request the Board to fix a record date. Pursuant to the
September 27, 1995 By-Law amendments, the Board shall promptly, but in all
events within 10 days after the date on which the request is received, adopt a
resolution fixing the record date for the solicitation. The By-Laws further
provide that such record date may not be before nor more than 15 days after the
date of the resolution.1 If the Board fails to set a record date on a timely
basis, a stockholder may fix the record date by the delivery of a signed consent
to the Company. On February 5, 1996, pursuant to DGCL Section 213(b) and in
accordance with the By-Laws, the Committee requested by written notice delivered
to the Secretary of the Company that the Board fix a record date for this
consent solicitation. On February 15, 1996, the Company announced that the Board
had set February 24, 1996, as the Record Date.
    
 
     If the Proposals are adopted pursuant to this consent solicitation, prompt
notice must be given by the Company pursuant to Section 228(d) of the DGCL to
stockholders who have not executed consents.
 
- ------------------
   
(1) The Committee believes that permitting the Board to set a record date 15
    days after the date of the resolution fixing such record date may be
    inconsistent with DGCL Section 213(b), which provides that the record date
    'shall not be more than ten days after the date upon which the resolution
    fixing the record date is adopted by the board of directors.'

EFFECTIVENESS AND REVOCATION OF CONSENTS
 
     The Committee's proposals will become effective when properly completed,
unrevoked consents are signed by the holders of record as of the Record Date of
a majority of the voting power of the then outstanding Common Stock and such
consents are delivered to the Company, provided that the requisite consents are
so delivered within 60 days of the date of the earliest dated consent so
delivered to the Company.
 
     An executed Consent Card may be revoked at any time by marking, dating,
signing and delivering a written revocation before the time signed, unrevoked
consents by the holders of more than 50% of the outstanding shares of Common
Stock on the Record Date have been delivered to the Company pursuant to DGCL
Section 228. A revocation may be in any written form validly signed by the
record holder as long as it clearly states that the consent previously given is
no longer effective. The delivery of a subsequently dated Consent Card which is
properly completed will constitute a revocation of any earlier consent. The
revocation may be delivered either to the Committee, in care of Morrow & Co.,
Inc., 909 Third Avenue, New York, New York 10022, or to the Company at 8700
Tesoro Drive, San Antonio, Texas 78217 or any other address provided by the
Company. Although a revocation is effective if delivered to the Company, the

Committee requests that either the original or photostatic copies of all
revocations of consents be mailed or delivered to the Committee as set forth
above, so that the Committee will be aware of all revocations and can more
accurately determine if and when the requisite consents to the actions described
herein have been received.
 
VALIDITY OF CONSENTS
 
     In connection with a consent solicitation, the By-Laws of the Company
require that the Company retain nationally recognized independent inspectors of
elections for the purpose of performing a ministerial review of the validity of
consents and any revocations thereof. Upon receipt by the inspectors of election
of all of the consents and revocations delivered to the Company in connection
with this consent solicitation, the By-Laws require the inspectors of election
to issue a preliminary report to the Company stating: (i) the number of shares
represented by valid and unrevoked consents; (ii) the number of shares
represented by invalid consents; (iii) the number of shares represented by
invalid revocations; and (iv) the number of shares entitled to submit consents
as of the Record Date. Unless the Company and the Committee agree to a shorter
or longer period, the Company and the Committee will have five days thereafter
to review the consents and revocations and to advise the inspectors and the
opposing party in writing as to whether they intend to challenge the preliminary
report. If no timely written notice of an intention to challenge the preliminary
report is received, the inspectors will certify the preliminary report (as
corrected or modified by virtue of the detection by the inspectors of clerical
errors) as their final report and deliver it to the Company. If the Company or
the Committee gives timely written notice of an intention to challenge the
preliminary report, a challenge session will be scheduled by the inspectors as
promptly as practicable. Following completion of the challenge session, the
inspectors will issue and deliver to the Company as promptly as practicable
their final report. Upon receipt of a final report from the inspectors, the By-
Laws require the Company to give prompt notice to the stockholders of the
results of this consent solicitation.
 
CONSENTS REQUIRED
 
   
     The consent of the holders of shares representing a majority of the votes
of all shares of Common Stock outstanding as of the Record Date is required to
adopt and approve each of the Committee's proposals. According to the Company,
there were 25,748,048 shares of Common Stock outstanding on the Record Date.
Each share of Common Stock entitles the Record-Date holder to one vote on the
Committee's proposals. Accordingly, written consents by Record-Date holders of
approximately 12,874,024 shares of Common Stock will be required to adopt and
approve each of the Committee's proposals.
    
 
   
     As of the Record Date, the Committee's members, the Committee Nominees and
their respective affiliates and associates beneficially owned an aggregate of
1,463,108 shares of Common Stock, constituting approximately 5.7% of the Common
Stock believed to be outstanding as of the Record Date, and expect to execute
(or cause to be executed) consents to all of the actions for which consents are
being solicited by the Committee with respect to all such shares. As a result,

in addition to the consents of the Committee's members and the Committee
Nominees, the unrevoked consents of other Record-Date holders owning
approximately 44.3% of the outstanding shares of Common Stock on the Record Date
are required to adopt the Proposals.
    
 
                                       7
<PAGE>
SOLICITATION OF CONSENTS
 
     Consents will be solicited by mail, telephone, telegraph, telex, facsimile
transmission, electronic mail and in person. Solicitations of consents will be
made by all or some of the Committee's members and the Committee Nominees.
 
     In addition, the Committee has retained Morrow & Co., Inc. to assist in the
solicitation and has executed an engagement letter with Morrow & Co., Inc.
providing for the payment of a fee of $150,000 plus reimbursement of expenses.
The engagement letter provides Morrow & Co., Inc. with indemnity from certain
liabilities, including liabilities arising under Federal securities laws. It is
anticipated that approximately 50 employees of Morrow & Co., Inc. will be
involved in soliciting the consents of stockholders in this consent
solicitation.
 
     Brokers, custodians, nominees and fiduciaries will be requested to forward
solicitation material to beneficial owners of the Common Stock. The Committee
will reimburse brokers, custodians, nominees and fiduciaries for their
reasonable expenses for sending solicitation material to the beneficial owners
of Common Stock.
 
   
     Subject to the following two paragraphs, the cost of solicitation will be
borne by the members of the Committee in equal proportions. Total expenditures
for the solicitation, including fees for attorneys, accountants, financial
advisers, solicitors, advertising, printing, transportation, litigation and
other costs incidental to the solicitation, are estimated to be approximately
$900,000. The total amount of such expenditures made to date is estimated to be
approximately $295,000, which amount includes expenditures incurred to date for
attorneys' fees and other costs incidental to the matters set forth below under
the caption 'CERTAIN LEGAL PROCEEDINGS.'
    
 
     Under an agreement between Mr. Washburn and Whelan, Mr. Washburn will be
entitled to receive a portion of the net profits, if any, from the exercise and
sale of 200,000 shares of Common Stock underlying certain options held by Whelan
if Mr. Washburn is not otherwise reimbursed for expenses incurred in connection
with this consent solicitation upon its termination. The amount payable to Mr.
Washburn will be equal to the lesser of (i) 30% of such net profits, if any,
realized upon exercise (or the deemed exercise and the sale thereof based on the
trading price of the Common Stock on the NYSE on the date the consent
solicitation is terminated) or (ii) the aggregate amount of such expenses funded
by Mr. Washburn as to which no reimbursement is received.
 
     The Committee will seek reimbursement of the costs of this solicitation
from the Company to the extent legally permissible. The Committee does not

intend that the question of the Company's reimbursement of solicitation expenses
will be submitted to a vote of stockholders unless such submission is required
by law.

                                   BACKGROUND
 
     Each of Messrs. Flannery, Stone and Washburn and Dr. Kaufman has been a
beneficial owner of Common Stock for at least four years, although the number of

shares beneficially owned by each has fluctuated. Those members of the Committee
invested in the Company because, at the time of their respective investments,
they saw fundamental values which they expected would eventually be reflected
through increases in stock prices. As already noted, however, the Committee
members have lost confidence in the ability of the incumbent Board to realize
those values.
 
     During 1992, when the Company was experiencing particularly severe
financial difficulties, the level of concern of Mr. Flannery and Dr. Kaufman
about their investments in the Company became acute. On October 30, 1992, Mr.
Flannery and Dr. Kaufman, together with certain other stockholders of the
Company, including Fraydan Manocherian, filed a statement on Schedule 13D
reporting, among other things, that the persons signing that Schedule 13D (the
'United Partners Reporting Persons') had reached, on October 26, 1992, 'an
understanding to act together under the name 'United Partners' in order to
attempt to protect and enhance the value of their shares of Common Stock,' and
had delivered a letter to the Company requesting that there be added to the
Company's Board of Directors two directors from a list of five designees, who
included Messrs. Flannery and Stone and Dr. Kaufman. On April 2, 1993, an
amendment to the Schedule 13D was filed which stated that as a result of the
Company's failure to respond to the October 26, 1992 letter, the United Partners
Reporting Persons were reviewing the options available, including engaging in a
proxy contest. No agreement or understanding between Mr. Flannery or Dr. Kaufman
and the other United Partners Reporting Persons was subsequently reached
regarding a proxy contest or the pursuit of any other option with regard to the
Company. In February 1994, each of Mr. Flannery and Dr. Kaufman formally
notified Mr. Manocherian of their withdrawal as participants in the Schedule 13D
filing group and the United Partners Reporting Persons filed an amendment to the
Schedule 13D reporting that, as a consequence of Dr. Kaufman's withdrawal, the
other participants had ceased to be the beneficial owners of 5% or more of the
Common Stock.
 
     In the weeks before the scheduled 1994 Annual Meeting of the Company's
stockholders, a decline in Common Stock prices resulted from several
developments affecting the Company, including a restructuring by the Company of
its outstanding debt and preferred stock on terms which Mr. Flannery, Mr.
Washburn and Dr. Kaufman independently concluded were contrary to the best
interests of stockholders. At the Company's 1994 Annual Meeting held on May 20,
1994, a representative of Messrs. Flannery and Washburn and Dr. Kaufman
nominated from the floor an alternative slate of directors consisting of Messrs.
Baker, Flannery and Washburn, Dr. Kaufman and another individual who is not a
member of the Committee or a Committee Nominee, but was unsuccessful in seating
any of those nominees.
 
     Events affecting the Company in early 1995, including the prospective sale
of a significant part of the Company's rights in the Bob West natural gas field,
led Dr. Kaufman and Mr. Flannery to conclude that another effort to unseat the
then-incumbent Board should be attempted at the forthcoming 1995 Annual Meeting.
During the week before the scheduled date for the 1995 Annual Meeting, Mr.
Flannery succeeded in obtaining revocable proxies for the meeting from several
other stockholders.
 
     At the Company's Annual Meeting held on May 4, 1995, a representative of
Mr. Flannery, Dr. Kaufman and the stockholders whose proxies were held by Mr.

Flannery nominated from the floor a dissident slate of six directors which
included Mr. Baker, Mr. Flannery, Dr. Kaufman, and three other individuals who
are not members of the Committee or Committee Nominees. Following the closing of
the polls, the inspectors of election
 
                                       9
<PAGE>
determined that they could not make a report on the vote at that time because of
the number of ballots and proxies submitted by stockholders at the meeting. On
May 15, 1995, the inspectors of election delivered a report showing that all of
the Board-approved nominees had been elected and all of the dissident nominees
had been defeated.
 
     As a result of what he perceived to be irregularities in the process by
which votes were taken, tallied, inspected and reported, Mr. Flannery, through
Whelan, the record holder of the shares of Common Stock then beneficially owned
by Mr. Flannery, formally challenged the reported results of the election. On
June 8, 1995, the inspectors of election denied Whelan's challenges, and on June
9, 1995 issued a second report confirming the results of the first report. That
second report indicated that with respect to three directorships, the average
difference in votes between the three Board-approved nominees receiving the
fewest votes and the three alternative nominees with the highest votes was
1,670,522 votes, or only 7.48% of the 22,303,905 shares present at the meeting,
in person or by proxy. In other words, a change in vote by holders of only
841,345 shares (or 3.7% of the shares present at the Annual Meeting) would have
elected three of the alternative nominees. In light of the advantages typically
enjoyed by incumbent management in annual elections of directors and the fact
that the dissident nominees were nominated from the floor without a formal
solicitation of proxies from stockholders generally, the Committee believes
those results are a strong indication of the breadth and depth of opposition to
the existing Board.
 
     On June 23, 1995, Whelan filed with the Court of Chancery of the State of
Delaware (New Castle County) an application for review of the election of
directors held at the Annual Meeting held in 1995, and the Court eventually
issued a ruling upholding the results of the election as reported by the
inspectors of election.
 
     The activities of Mr. Flannery and Dr. Kaufman relating to the 1995 Annual
Meeting were conducted with the guidance of legal counsel, and each believes
that his activities were in compliance with all applicable laws.
 
   
     Following the decision of the Delaware Chancery Court upholding the results
of the 1995 election, Mr. Flannery and Dr. Kaufman continued to believe strongly
that the Company's management was seriously deficient. As a result of his role
at the Annual Meetings held in 1994 and 1995, Mr. Flannery was periodically
contacted by dissatisfied stockholders voicing their complaints against
incumbent management and, in some cases, encouraging him to take further steps
to attempt to change the direction of the Company's management; however, as a
result of the time, effort and expense which Mr. Flannery knew would be required
in order to mount another effort to challenge the Board, he was reluctant to do
so. In August 1995, however, the Texas Supreme Court rendered a decision in the
litigation between the Company and the Tennessee Gas Pipeline Company (which is

more fully described in the 1995 Company Proxy Statement) that Mr. Flannery
considered unfavorable to the Company. Furthermore, the closing prices of the
Common Stock on the NYSE had declined since the election loss by the dissidents
at the 1995 Annual Meeting, from $10 7/8 per share of Common Stock on the day
before the 1995 Annual Meeting to $9 per share on December 22, 1995, the last
trading day before this consent solicitation became publicly known, and had
reached a low for the year of $7 3/8 on October 5, 1995. As the result of these
events, as well as the continued urging of other stockholders, Mr. Flannery
began in September 1995 to consider more seriously various options for
influencing or replacing the incumbent Board. His deliberations included
discussions with Messrs. Baker, Stone and Washburn and Dr. Kaufman.
    
 
     Those discussions were informal, general and exploratory, and no agreement
or understanding was reached until December 14, 1995, at which time Messrs.
Baker, Flannery, Stone and Washburn and Dr. Kaufman orally agreed to form the
Committee in order to pursue removal and replacement of the Company's entire
Board of Directors. In view of the expense and intense effort associated with a
consent solicitation in opposition to incumbent management, each Committee
member's decision was made after lengthy deliberation and with reluctance. In
the final analysis, the Committee concluded that there was no other choice.
After discussions with Committee members, Mr. Galloway and Mr. Thompson agreed
to become Committee Nominees. In certain pleadings filed by the Company in
connection with the litigation described below under the caption 'CERTAIN LEGAL
PROCEEDINGS,' the Company alleges 'upon information and belief, [that] the
members of the [Committee] have had an understanding and an agreement since
1994, and perhaps sooner, to attempt to effect a change in the control of the
[Board].'
 
     On December 26, 1995, the Committee filed with the Commission, within the
period provided by law, a Statement on Schedule 13D disclosing formation of the
Committee and its intention to commence this consent solicitation.
 
                                       10
<PAGE>
   
     During several conversations that occurred between mid-September and early
November in 1995, Mr. Baker and Mr. Flannery have each at various times
discussed with Ardsley Advisory Partners ('Ardsley'), the Company's largest
stockholder, the possibility that Ardsley might sell options to purchase some of
the shares of Common Stock held by Ardsley. On November 16, 1995, Whelan
purchased from Ardsley options to acquire up to 400,000 of the shares of Common
Stock held by Ardsley. As part of the oral agreement reached on December 14,
1995, Whelan sold to each of Messrs. Baker and Stone corresponding options
written by Whelan to acquire 100,000 of the shares of Common Stock covered by
the options written by Ardsley. In certain pleadings filed by the Company in
connection with the litigation described below under the caption 'CERTAIN LEGAL
PROCEEDINGS,' the Company alleges that 'the terms of these extraordinary option
grants leave no doubt as to their true purpose--to provide financial assistance
to the Whelan Group in order to help defray the anticipated costs of a consent
solicitation to unseat the incumbent Board. Thus, for a purchase price of $.09
per share (or $36,000 in the aggregate), Ardsley purported to grant Whelan
options to purchase for $8.25 per share (or $.625 lower than the closing market
price on January 5, 1996) up to 400,000 shares (enough to push the Whelan

Group's holdings over the 5% threshold for Schedule 13D filing purposes), which
if exercised today would yield in excess of $250,000 in profits. The options are
only exercisable, however, until May 16, 1996 (shortly after the anticipated
date of the 1996 Annual Meeting). The options are intended to provide plaintiffs
with the best of both worlds: in the event the Whelan Group is unsuccessful in
its consent solicitation, it will be able to use the profits realized upon the
exercise and the subsequent sale of shares to defray the costs of their
unsuccessful solicitation. However, if the consent solicitation succeeds, the
Whelan Group has stated that it intends to seek reimbursement for such expenses
directly from the Company (without stockholder approval unless mandated by law),
in which case there will be no need to exercise the Ardsley options to defray
plaintiffs' costs. Any profits realized upon exercise and sale in such case
would present a windfall to Whelan. In light of Ardsley's enthusiastic financial
and other support of the Whelan Group's efforts, as well as the extraordinary
terms of the option grant to Whelan, it is obvious that an arrangement or
understanding beyond the mere grant of the options themselves exists between
Ardsley and the other members of the Whelan Group, and that Ardsley's role
extends far beyond the normal role played by a passive institutional investor.'
    
 
   
     By letter dated February 7, 1996, Mr. Flannery, as a record holder of
shares of Common Stock, requested that the Company provide a list of
stockholders and other stockholder information to enable the Committee to
undertake this Consent Solicitation and for other valid purposes. Pursuant to an
agreement between Mr. Flannery and the Company, the Company has provided Mr.
Flannery with the requested information.
    
 
                           CERTAIN LEGAL PROCEEDINGS
 
     On December 26, 1995, the Committee commenced a lawsuit in the United
States District Court for the Western District of Texas, San Antonio Division,
against the Company and its Chief Executive, Bruce A. Smith (collectively,
'Defendants'). The action seeks, among other relief, a judgment (i) declaring
that the Company's 'poison pill' plan does not apply to the efforts of the
Committee to solicit consents from other stockholders of the Company; (ii)
declaring that the Company's By-Laws permit removal of directors through
stockholder action by written consent; (iii) enjoining the Company from delaying
or otherwise unlawfully interfering with the efforts of the Committee to solicit
consents from other stockholders; and (iv) declaring that the actions and
disclosures of the Committee with regard to their effort to solicit consents are
and have been in compliance with the Securities Exchange Act of 1934, as amended
(the 'Exchange Act').
 
   
     On January 8, 1996, Defendants filed their Answer and Counterclaim to the
Committee's Complaint. Defendants' counterclaim alleges, inter alia, that the
Committee's Schedule 13D, filed on December 26, 1995, violated Section 13(d) of
the Exchange Act by (i) not including Ardsley as part of the 13D group and not
including in the 13D group certain of the wives and children of the Committee
members who held shares of Tesoro directly or in trust, (ii) not filing a
Schedule 13D earlier disclosing that a 13D group had already been formed
purportedly in 1994 and (iii) making purported false and misleading statements

in preliminary consent materials filed with the SEC. Defendants' counterclaim
also alleges that the preliminary consent materials filed with the SEC on
December 26, 1995 by the Committee contained purported false and misleading
statements in violation of Section 14(a) of the Exchange Act. On that same day,
Defendants filed a motion seeking a temporary restraining order and preliminary
injunction and then sought and obtained an ex parte temporary restraining order
enjoining the Committee from (i) soliciting or attempting to solicit written
consents of the Company's
    
 
                                       11
<PAGE>
stockholders, (ii) filing or disseminating to stockholders or the public any
Schedule 13D or 14A Statements regarding the Company and (iii) taking any
temporary further steps in furtherance of their consent solicitation effort.
 
     Defendants based their application for an ex parte temporary restraining
order and for a preliminary injunction upon their allegations (1) that the draft
Consent Solicitation Statement, which had not been disseminated to the Company's
stockholders, was in violation of Section 14(a) of the Exchange Act in that it
contained various false and misleading statements and omissions that would
likely result in 'confusion' and misunderstanding on the part of the Company's
stockholders and (2) that the proposed solicitation was a 'midnight raid' which
could force the removal of the Company's present Board of Directors without any
opportunity either to rebut the disclosures in the Consent Statement or seek
relief from the Courts. A number of the Company's specific allegations are
discussed in detail in this Consent Solicitation Statement.
 
     On January 16, 1996, the Committee moved to dissolve the ex parte temporary
restraining order because, inter alia, it was in violation of Rule 65 of the
Federal Rules of Civil Procedure, was unprecedented in scope and was contrary to
the purposes of the Williams Act. On the next day, January 17, 1996, the Court
denied the Committee's motion to dissolve the ex parte temporary restraining
order.
 
     On January 19, 1996, Defendants moved for an order extending the temporary
restraining order, which order was granted on that same day. On January 24,
1996, the Court scheduled a hearing on Defendants' preliminary injunction motion
for January 31, 1996. On January 31, 1996, a hearing was held on Defendants'
preliminary injunction motion. On February 1, 1996, the Court signed an order
which was entered on February 2, 1996, and which vacated the temporary
restraining order and denied Defendants' motion for preliminary injunction.

</TABLE>
    
 
- ------------------
 
(1) For purposes of this table, the number of shares which a person or group of
    persons is deemed to 'beneficially own' includes any shares that such person
    has the right to acquire within 60 days. For purposes of computing the
    percentage of outstanding shares held by each person or group of persons
    named above on a given date, any security that such person or persons has
    the right to acquire within 60 days is deemed to be outstanding, but is not
    deemed to be outstanding for the purpose of computing the percentage
    ownership of any other person. Such computations are based on information
    concerning the number of shares of Common Stock issued and outstanding as of
    October 31, 1995, as reported by the Company in the 1995 Third Quarter 10-Q.
 
   
(2) The shares shown include (i)(A) 140,615 shares held by Whelan Management,
    Inc. ('Whelan'), of which Mr. Flannery is the principal executive officer
    and a 75% common stockholder and (B) 200,000 shares which Whelan has the
    right to acquire through the exercise of stock options which were
    exercisable on February 29, 1996, or within 60 days thereafter, (ii) 18,357
    shares held by the Sean Kenrick Flannery Trust of which Mr. Flannery is the
    investment officer and (iii) 2,600 shares of Common Stock owned by Mr.
    Flannery's wife. Mr. Flannery disclaims beneficial ownership of the shares
    owned by his wife. The shares shown do not include shares that Whelan
    Securities Inc., in the ordinary course of its business as a broker-dealer,
    has purchased and sold for the accounts of its customers, as to which Mr.
    Flannery disclaims beneficial ownership. Mr. Flannery has advised the
    Committee that all such customer accounts are non-discretionary and that
    neither Whelan nor Whelan Securities Inc. has any control over buying,
    selling or voting shares of Common Stock in such accounts. As a result,
    Whelan Securities Inc. or its clearing agent may be the record owner of
    certain of such shares of Common Stock over which it does not exercise
    beneficial ownership.
    
 
   

(3) The shares shown include 100,000 shares which Mr. Baker has the right to
    acquire through the exercise of stock options which were exercisable on
    February 29, 1996, or within 60 days thereafter.
    
 
(4) The shares shown include (i) 581,500 shares owned by Dr. Kaufman either
    directly or through an individual retirement account, (ii) 20,000 shares
    held by the Kaufman Children's Trust, of which Dr. Kaufman is the sole
    trustee and (iii) 10,500 shares owned by Dr. Kaufman's wife. Dr. Kaufman
    disclaims beneficial ownership of the shares in the Kaufman Children's Trust
    and the shares owned by his wife.
 
   
(5) The shares shown include 100,000 shares which Mr. Stone has the right to
    acquire through the exercise of stock options which were exercisable on
    February 29, 1996, or within 60 days thereafter.
    
 
(6) The shares shown include 39,545 shares held by the Robert S. and Suzanne P.
    Washburn Revocable Trust of which Mr. Washburn is a co-trustee, and 193,791
    shares held by the Robert S. Washburn Money Purchase Pension and Profit
    Sharing Keogh Plan Trust, of which Mr. Washburn is the sole trustee. Mr.
    Washburn exercises shared voting and investment power with respect to the
    Common Stock held by the Robert S. and Suzanne P. Washburn Revocable Trust.

     C.  Except as otherwise described herein, no member of the Committee,
Committee Nominee or 'associate' of any of the foregoing owns securities of the
Company of record but not beneficially.
 
   
     D.  The following table sets forth shares of Common Stock, Preferred Stock
and Exchange Notes of the Company purchased or sold within the past two years by
each of the members of the Committee, the Committee Nominees, Whelan, the Sean
Kenrick Flannery Trust referred to in note (2) to the table under paragraph B
above or either of the two trusts of which Mr. Washburn is a trustee referred to
in note (6) to the table under paragraph B above, the dates on which they were
purchased or sold and the amount purchased or sold on each such date. In the
tables below, the term 'Preferred Stock' shall mean the Company's $2.16
Cumulative Convertible Preferred Stock, which is no longer outstanding, and
'Exchange Notes' shall mean the Company's 13% Exchange Notes due December 1,
2000. Transaction dates listed are trade dates except for those marked with a
'+', which denotes a settlement date. The tables do not reflect the purchase on
November 16, 1995, by Whelan from Ardsley of options to acquire up to 400,000 of
the shares of Common Stock held by Ardsley or the sale on December 22, 1995, by
Whelan to each of Mr. Baker and Mr. Stone of corresponding options written by
Whelan to acquire 100,000 of the shares of Common Stock covered by the options
written by Ardsley. See 'BACKGROUND' in the Consent Solicitation Statement to
which this Appendix is attached.

     This Appendix sets forth the text, in relevant part, of the By-Laws which
are proposed by the Committee to be amended, as the Company's public filings
indicate such By-Laws were in effect on November 14, 1995 and as they will
appear after adoption of the Committee's proposed By-Law Amendments. Language
proposed to be deleted is marked in brackets. Language proposed to be added is
underlined. The Committee is not aware of any amendments to the By-Laws since
November 14, 1995. To the extent any such By-Law amendments have been adopted
subsequently, such intervening amendments shall be repealed by the adoption of
the following amendments if inconsistent therewith.
 
     Section 2.1  Number, Election and Term of Office.  The number of directors
which shall constitute the whole Board of Directors shall be five, unless and
until changed by resolution of the Board of Directors [fixed from time to time
by resolution of the Board of Directors but shall not be less than three]. The
directors shall be elected at the annual meeting of stockholders, except as
provided in Section 2.2, and each director elected at an annual meeting of
stockholders, and directors elected or appointed in the interim to fill
vacancies and newly created directorships shall hold office until the next
annual meeting of stockholders and [or] until their successors are duly elected
and qualified or until their earlier resignation or removal. A director need not
be a stockholder.
 
     Section 2.2  Vacancies and Additional Directorships.  Any vacancy or
vacancies created by the death or resignation of a director may be filled only
by the majority vote of the remaining directors, though less than a quorum, or
by the sole remaining director. Any vacancy or vacancies created by the removal
of one or more directors may be filled only by action of the holders of shares
representing a majority of the shares of Common Stock outstanding and entitled
to vote and such action may be taken at the same annual or special meeting, or
by means of the same written consent or consents, of stockholders at or by which
such director or directors were removed, or may be taken at a different meeting
or by a separate written consent or consents. Newly created directorships
resulting from any increase in the authorized number of directors shall be
filled only by a majority of the directors then in office, though less than a
quorum, or by the sole remaining director, and such newly created directorships
may not be filled by the stockholders unless otherwise required by law. [Unless
otherwise provided in the Certificate of Incorporation or these By-Laws: (1)
vacancies and newly created directorships resulting from any increase in the
authorized number of directors elected by all of the stockholders having the
right to vote as a single class may be filled by a majority of the directors
then in office, although less than a quorum; and (2) whenever the holders of any
class or classes of stock or series thereof are entitled to elect one or more
directors by the Certificate of Incorporation, vacancies and newly created
directorships of such class or classes or series may be filled by a majority of
the directors elected by such class or classes or series thereof then in
office.]
 
     Section 2.7  Removal of Directors.  At any annual meeting of stockholders,
at any special meeting of the stockholders duly called for the purpose of
removing a director or directors as provided in these By-Laws, or by action of
the stockholders by written consent in accordance with the laws of the State of

Delaware and the Certificate of Incorporation, any director or directors may, by
the affirmative vote or written consent, as the case may be, of the holders of
shares representing a majority of [the votes of all] the shares of Common Stock
[stock] outstanding and entitled to vote [for the election of directors], be
removed from office, either for or without cause. Such vacancy [shall] may only
be filled by the stockholders [directors] as provided in Section 2.2.

                   STOCK HOLDINGS OF THE COMPANY'S MANAGEMENT
 
     Schedule 14A adopted by the Commission under the Exchange Act requires the
Committee to disclose, to the extent known to the Committee, certain information
regarding ownership of voting securities of the Company. The information set
forth in this Appendix is provided in response to that requirement. Except with
respect to information concerning the Committee and its members, all information
contained in the following tables (including the footnotes) has been taken from
or is based upon the Joint Proxy Statement/Prospectus of Coastwide Energy
Services, Inc. and Tesoro Petroleum Corporation, dated January 20, 1996 (the
'Coastwide Proxy Statement'), and other information contained in other filings
by the Company with the Commission.
 
   
     The following table shows the beneficial ownership of the Company's Common
Stock as reported to the Company as of December 31, 1995, including shares as to
which a right to acquire ownership exists (for example, through the exercise of
stock options or stock awards) within the meaning of Rule 13d-3(d)(1) under the
Exchange Act for each director of the Company, the Company's Chief Executive
Officer, the other four most highly compensated officers of the Company during
1995 and, as a group, such persons and other executive officers. The calculation
of the percentage of outstanding shares of Common Stock is based on the number
of outstanding shares of Common Stock as of the Record Date. 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.

- ------------------
   
(1) According to a Schedule 13G, as amended, filed with the Commission, Ardsley
    beneficially owns 2,560,000 shares of Common Stock and is a general
    partnership organized under the laws of the State of Connecticut and an
    investment adviser registered under Section 203 of the Investment Advisers
    Act of 1940, as amended (the 'Act'). In its Schedule 13G, Ardsley claims
    that, with respect to the shares of the Company's Common Stock held by
    Ardsley, it acts as investment advisor for the discretionary accounts of
    certain clients, including (i) investment partnerships for which Ardsley
    serves as the management company and (ii) a general partnership comprised of
    the same partners as Ardsley serves as general partner. By reason of the
    provisions of Rule 13d-3 under the Exchange Act, Ardsley is deemed to own
    beneficially the shares owned by the managed accounts. Each client for whose
    account Ardsley had purchased the Company's Common Stock has the right to
    receive or the power to direct the receipt of dividends from, or the

    proceeds from the sale of, such shares purchased for his account. No such
              client has any of the foregoing rights with respect to more than 5

(Footnotes continued from previous page)
    percent of the Company's Common Stock. According to its Schedule 13G,
    Ardsley states that there is no agreement or understanding among such
    persons to act together for the purpose of acquiring, holding, voting or
    disposing of any such securities. Philip J. Hempleman, a managing partner of
    Ardsley, is a citizen of the United States. By virtue of Mr. Hempleman's
    position as managing partner of Ardsley, he may be deemed to have the shared
    power to vote, or direct the voting of, and the shared power to dispose, or
    direct the disposition of, shares of the Company's Common Stock held by the
    discretionary accounts managed by Ardsley, and, therefore, Mr. Hempleman may
    be deemed to be the beneficial owner of such shares.
 
   
(2) According to Schedule 13Ds on file with the Commission, Oakville is a wholly
    owned subsidiary of Kuo Investment Limited, a Cayman Islands corporation
    ('Kuo'). According to information provided to the Company by Oakville, the
    following persons are Oakville's directors and executive officers: (a) Peter
    Yun Siak Fu, President and Director of Oakville; Director and officer of
    Kuo; (b) Peter Chong Cheng Fu, Director and Secretary of Oakville; Director
    and officer of Kuo; (c) Ong Beng Seng, Vice President and Director of
    Oakville; Director and officer of Kuo; (d) David Song Long Ban, Treasurer
    and Director of Oakville; Director and officer of Kuo; (e) Steven H.
    Grapstein, Vice President and Director of Oakville; and (f) Holland
    Intertrust (Curacao) N.V., a Netherlands Antilles corporation, a Director of
    Oakville. Oakville reports that it has sole voting and dispositive power
    over its voting securities of the Company.
    
 
     As stated under the caption 'BACKGROUND' in the Consent Solicitation
Statement to which this Appendix is attached, on November 16, 1995, Whelan
purchased from Ardsley options to acquire up to 400,000 shares of Common Stock
from Ardsley, and the foregoing table does not reflect that transaction, nor any
other changes to beneficial ownership of Common Stock which may have occurred
since December 31, 1995.

                 THE STOCKHOLDERS' COMMITTEE FOR NEW MANAGEMENT
                       OF TESORO PETROLEUM CORPORATION IN
                      OPPOSITION TO THE BOARD OF DIRECTORS
                        OF TESORO PETROLEUM CORPORATION
    
 
   
    Unless otherwise indicated below, the undersigned, a stockholder of record
of Tesoro Petroleum Corporation, a Delaware corporation (the 'Company'), on
February 24, 1996 (the 'Record Date'), hereby consents pursuant to Section
228(a) of the Delaware General Corporation Law with respect to all shares of
common stock, par value $0.16-2/3 per share (the 'Common Stock'), of the Company
held by the undersigned to the taking of each of the following actions without a
meeting, without prior notice and without a vote:
    
 
    THE STOCKHOLDERS' COMMITTEE FOR NEW MANAGEMENT OF TESORO PETROLEUM
CORPORATION STRONGLY RECOMMENDS THAT THE STOCKHOLDERS OF THE COMPANY CONSENT TO
ALL OF THE FOLLOWING RESOLUTIONS. EACH OF THE RESOLUTIONS REQUIRES THE APPROVAL
OF A MAJORITY OF THE COMMON STOCK OUTSTANDING ON THE RECORD DATE.
 
    THIS CONSENT CARD IS CONTINUED ON THE REVERSE SIDE. PLEASE MARK, SIGN AND
DATE THIS CONSENT CARD ON THE REVERSE SIDE BEFORE RETURNING THIS CONSENT CARD IN
THE ENCLOSED ENVELOPE.
 
1.A.  FIX THE NUMBER OF DIRECTORS AT FIVE (5).
 
    RESOLVED, that Section 2.1 of Article II of the By-Laws be amended to read
as follows:
 
   
        Section 2.1  Number, Election and Term of Office.  The number of
    directors which shall constitute the whole Board of Directors shall be five,
    unless and until changed by resolution of the Board of Directors. The
    directors shall be elected at the annual meeting of stockholders, except as
    provided in Section 2.2, and each director elected at an annual meeting of
    stockholders, and directors elected or appointed in the interim to fill
    vacancies and newly created directorships, shall hold office until the next
    annual meeting of stockholders and until their successors are duly elected
    and qualified or until their earlier resignation or removal. A director need
    not be a stockholder.

        Section 2.2  Vacancies and Additional Directorships.  Any vacancy or

    holders of shares representing a majority of the shares of Common Stock
    outstanding and entitled to vote and such action may be taken at the same
    annual or special meeting, or by means of the same written consent or
    consents, of stockholders at or by which such director or directors were
    removed, or may be taken at a different meeting or by a separate written
    consent or consents. Newly created directorships resulting from any increase
    in the authorized number of directors shall be filled only by a majority of
    the directors then in office, though less than a quorum, or by the sole
    remaining director, and such newly created directorships may not be filled
    by the stockholders unless otherwise required by law.

        Section 2.7  Removal of Directors.  At any annual meeting of
    stockholders, at any special meeting of the stockholders duly called for the
    purpose of removing a director or directors as provided in these By-Laws, or
    by action of the stockholders by written consent in accordance with the laws
    of the State of Delaware and the Certificate of Incorporation, any director
    or directors may, by the affirmative vote or written consent, as the case
    may be, of the holders of shares representing a majority of the shares of
    Common Stock outstanding and entitled to vote, be removed from office,

               THE STOCKHOLDERS' COMMITTEE FOR NEW MANAGEMENT OF
                          TESORO PETROLEUM CORPORATION
                          C/O WHELAN MANAGEMENT CORP.

                                                               February 29, 1996
    
 
Dear Fellow Tesoro Petroleum Stockholder:
 
   
     The Stockholders' Committee for New Management of Tesoro Petroleum
Corporation (the 'Committee') beneficially owns approximately 5.7% of the
outstanding Common Stock of Tesoro Petroleum Corporation (the 'Company'). We
believe that many of the Company's stockholders share the Committee's profound
disappointment with the performance of the Company's stock and the Company's
Board of Directors (the 'Board'). As described in the accompanying Consent
Solicitation Statement, we are seeking your consent to remove all seven of the
present members of the Board, and to elect George F. Baker, Gale L. Galloway,
Alan J. Kaufman, M.D., James H. Stone and Douglas B. Thompson as directors of
the Company (collectively, the 'Committee Nominees').
    
 
                THE ALASKAN REFINING BUSINESS SHOULD BE DIVESTED
 
   
     The Committee believes that current and recent trading prices of the Common
Stock do not adequately reflect the value of the Company's underlying businesses
and assets. In the Committee's opinion, the principal reason for that
discrepancy is the fact that the Company is primarily engaged in two businesses,
(i) petroleum refining and marketing in Alaska (the 'Refining Business') and
(ii) natural gas exploration and production in Texas and Bolivia (the 'E & P
Business'), which have distinctly separate financial, operating and investment
characteristics. Unfortunately, they also have quite different financial
performance records, as made clear by the following table which shows the
operating profit (loss) and capital expenditures in respect of the Refining
Business and the E & P Business for each of the years 1992 through 1995:

</TABLE>
    
 
- ------------------
   
(1) Includes gain on sale of assets of $5.8 million.
    
 
   
(2) Includes (i) a refund of $8.5 million received in settlement of a tariff
    dispute, (ii) a gain of $2.4 million from the sale of assets, (iii)
    favorable feedstock cost adjustments of $1.5 million and (iv) charges of
    $6.6 million for environmental contingencies and other matters.
    
 
   
(3) Includes $33 million gain from sale of certain interests in the Bob West
    Field.
    
 
   
     Obviously, the E & P Business is a strong financial performer, and the
Company's overall operating results have been dragged down by the erratic
Refining Business which, after excluding gains on the sale of assets and other
non-recurring gains and losses, lost an aggregate of $2.4 million during the
past four years.
    
 
   
     As noted in the above chart, during 1994 and 1995, the Company made $32
million and $9.3 million, respectively, in capital expenditures for the Refining
Business. Moreover, the Company has budgeted an additional $9 million in capital
expenditures related to the Refining Business for 1996. Also, according to the
1995 Third Quarter 10-Q, another $10 million will be required in 1997 to comply
with environmental laws. We think that all of that money would be better spent
if used to reduce the Company's high-cost debt or to develop the Company's E & P
Business.
    
 
   
     We think that a divestiture of the Refining Business would have several
benefits for stockholders. The stock market would be able to value the Common
Stock based on the strong positive operating profits of the
    
<PAGE>
   
Company's continuing E & P Business. If the divestiture took the form of a sale,
the proceeds could be used to reduce the Company's high-cost debt, directly and
immediately increasing the value of stockholders' investments. Money which
otherwise would be needed for capital expenditures for the Refining Business
could be used to reduce debt or take other actions to enhance stockholder value
immediately. We also think that the Company's management has been distracted by
the many problems experienced by the Refining Business during the past several

years. There can be no assurance, however, that, if elected, the Committee
Nominees will be able to effectuate a divestiture of the Refining Business under
terms that would be beneficial to the Company and its stockholders. The ability
of the Committee Nominees to effectuate a divestiture of the Refining Business
under terms that would be beneficial to the Company and its stockholders is
subject to a number of significant uncertainties, including the then prevailing
and prospective levels of the Refining Business earnings and cash flow as well
as general business and economic conditions in the petroleum refining and
marketing industry. Because the Committee Nominees have not had access to the
Company's books, records, property or personnel, they have not been able to
fully assess the difficulties that may be encountered in attempting to
consummate the proposed transaction. It is the Company's position, as stated in
certain of its pleadings in the litigation described in the Consent Solicitation
Statement under the caption 'CERTAIN LEGAL PROCEEDINGS,' that 'market conditions
on the West Coast are such that the refinery cannot 'promptly' be sold; numerous
other refineries are known to be on the market at this time for which there are
no buyers. Nor is it likely at the present time that the refinery could be sold
at a commercially reasonable price let alone anywhere near the price fantasized
by the [Committee]. It is unlikely that a sale of the refinery could cover the
approximately $90 million in debt associated with the refinery, let alone cover
the additional environmental costs or have excess funds available for
refinancing or repayment of other debt.'
    
 
   
     The Committee believes there is an opportunity to increase value for
stockholders by divesting the Refining Business and focusing on the core
business of exploiting the Company's valuable interests in the Bob West and
Bolivian fields. The Committee Nominees, if elected, intend to seek stockholder
approval of any proposed divestiture of the Refining Business.
    
 
   
                             CONSENT CONSIDERATIONS
    
 
   
     The following factors, taken together with the information provided
elsewhere in this letter and the accompanying Consent Solicitation Statement,
should be considered carefully in determining whether to consent to the removal
of the Board and the election of the Committee Nominees:
    
 
   
     The Committee Nominees have not reached a conclusion regarding the method
or process pursuant to which the Refining Business would be sold. Additionally,
Messrs. Thompson and Galloway, who are not members of the Committee but who are
Committee Nominees, have not reached a conclusion as to whether to sell the
Refining Business. Also, there can be no assurance that, if elected, the
Committee Nominees will be able to effectuate a divestiture of the Refining
Business under terms that would be beneficial to the Company and its
stockholders. The ability of the Committee Nominees to effectuate a divestiture
of the Refining Business under terms that would be beneficial to the Company and
its stockholders is subject to a number of significant uncertainties, including

the then prevailing and prospective levels of the Refining Business earnings and
cash flow as well as general business and economic conditions in the petroleum
refining and marketing industry.
    
 
   
     While the Committee thinks that a disposition of the Refining Business and
the use of all or part of any sale proceeds to reduce debt or the other steps to
be considered will have a favorable impact on stockholder value, the trading
price of the Common Stock is, of course, influenced by many factors and,
therefore, it is impossible to say with certainty that its price will increase
or to predict the amount of any such increase that might occur. Additionally,
because the Committee Nominees have not had access to the Company's books,
records, property or personnel, they have not been able to fully assess the
difficulties that may be encountered in attempting to consummate the proposed
transaction and are not in a position at this time to prepare and present herein
pro forma financial information, nor have they prepared written analyses, that
would demonstrate the impact that the sale of the Refining Business would have
on the financial statements of the Company.
    
 
   
     As discussed below, the Committee believes that, if the Committee Nominees
conclude, after their election to the Board, to pursue a sale of the Refining
Business or other assets, a reduction of the Company's high-cost debt would be a
profitable use of all or part of the proceeds. The Company has stated, however,
that it does not believe it would be prudent to attempt to refinance the
Company's outstanding debt at this time.
    
 
                                       2
<PAGE>
                            THE COMMITTEE'S PROGRAM
 
     The Committee Nominees are experienced businessmen who have no prior
relationship with or allegiance to any members of the Company's senior
management. Each of the Committee Nominees has a substantial background in
business, finance or investing. Messrs. Galloway, Stone and Thompson are, we
think, very knowledgeable about the oil and gas industry, and Mr. Galloway has a
proven track record in turning around underperforming companies within that
industry. The Committee Nominees are committed to taking appropriate steps to
maximize values for all stockholders as promptly as possible after their
election.
 
     The knowledge of the Committee Nominees concerning the Company is not as
complete as it would be if they were already Board members. Accordingly, if
elected, the Committee Nominees will conduct a detailed review of the Company
and its assets, corporate structure, capitalization, operations, properties,
policies and personnel in order to develop strategies to enhance stockholder
value.
 
   
     While we cannot now know the specifics of those strategies, based on our
current knowledge of the Company and its businesses, assets and operations, we

expect that a majority of the Committee Nominees, once elected, will (subject to
their fiduciary obligations and based upon the information then available):1
    
 
   
               o DEVELOP A PLAN FOR THE DISPOSITION OF THE COMPANY'S REFINING
                 BUSINESS THROUGH A SALE TO ONE OR MORE BUYERS, A SPIN-OFF OR
                 SOME OTHER MEANS.  The Committee Nominees have not reached a
                 conclusion regarding the method or process pursuant to which
                 the Refining Business would be sold. Additionally, the
                 Committee Nominees have no intention of selling the Refining
                 Business, or any other assets or businesses of the Company, to
                 the Committee, any of its members or any of their affiliates.
                 Further, the Committee Nominees do not presently intend or
                 contemplate that, if elected, they would enter into any
                 agreements or transactions with members of the Committee or any
                 of their affiliates, although such agreements or transactions
                 are possible. The Committee Nominees are aware, as described
                 below, that, to the extent Mr. Flannery were asked to and were
                 instrumental in assisting the Company in arranging for the sale
                 of some or all of the Company, he may expect to receive a
                 commercially reasonable fee. Although the Committee Nominees
                 have not considered whether, if elected, they would cause the
                 Company to enter into any agreement with Mr. Flannery to engage
                 his services in connection with the sale of the Refining
                 Business, or any other assets or businesses of the Company, it
                 is possible that such an agreement may be entered into.
    
 
               o FULLY EVALUATE ALL ALTERNATIVES.  We anticipate that the
                 Committee Nominees will also proceed to dispose of other
                 non-productive assets that are unrelated to the core E & P
                 Business. They will engage in an in-depth analysis of the
                 Company's operations in an effort to identify opportunities for
                 reducing corporate overhead and general administrative expenses
                 and strengthening and improving the core E & P Business. Our
                 nominees will thoroughly review the Company's management and
                 make such changes as they conclude are in the best interests of
                 stockholders.
 
               o THE COMMITTEE IS COMMITTED TO STOCKHOLDER
                 DEMOCRACY.  Stockholders, as the true owners of the Company,
                 should be able to freely elect and change the individuals
                 serving on the Board and should also be able to decide for
                 themselves whether to accept or reject third-party bids for the
                 entire Company. If elected, the Committee Nominees intend to
                 abolish devices such as the Company's 'poison pill' and the
                 amendments to the By-Laws adopted by the incumbent Board which,
                 in the opinion of the Committee, limit the ability of
                 stockholders to participate in or control important corporate
                 decisions. Additionally, if elected, the Committee Nominees
                 have agreed to forgo and not receive in their respective
                 capacities as directors any cash director
 

- ------------------
   
1. Messrs. Thompson and Galloway, who are Committee Nominees but who are not
   members of the Committee, have not reached any determination with respect to
   the Committee's program, but will, if elected, review and consider all facets
   of the proposed program.
    
 
                                       3

   fees or any retirement benefits currently enjoyed by the Board. They intend,
   however, to structure director compensation in the form of stock and/or stock
   options.
 
   
               o REDUCE OR REFINANCE DEBT.  The Committee believes that the
                 Company is burdened by long-term debt, including the Company's
                 12 3/4% Subordinated Debentures and 13% Exchange Notes. At the
                 end of 1995, the Company had approximately $153 million in
                 outstanding long-term indebtedness, of which approximately $30
                 million represented the outstanding aggregate principal amount
                 of the 12 3/4% Subordinated Debentures and approximately $44
                 million represented the outstanding aggregate principal amount
                 of the 13% Exchange Notes. If the Committee Nominees conclude,
                 after their election to the Board, to pursue a sale of the
                 Refining Business or other assets, we believe that in the
                 existing interest rate and investment environment and given
                 other currently prevailing conditions, reduction of the
                 high-cost debt, particularly the Company's 12 3/4% Subordinated
                 Debentures and 13% Exchange Notes, would be a profitable use of
                 all or part of the proceeds. For example, for each $10 million
                 aggregate reduction in outstanding principal amount of the
                 Company's 12 3/4% Subordinated Debentures and 13% Exchange
                 Notes, the Committee believes that, assuming a blended interest
                 rate of 12 7/8%, the Company would reduce its annual interest
                 expense by approximately $1,287,500, which would result in an
                 after-tax increase in annual operating profit of at least
                 $836,875, assuming the maximum corporate tax rate of 35%. Of
                 course, the Committee's Nominees also will consider the
                 feasibility of refinancing all or part of the Company's
                 outstanding debt in order to reduce debt service costs. As
                 discussed in footnote 2 below, the Company has stated that it
                 does not believe it would be prudent to attempt to refinance
                 its debt at this time.2
    
 
- ------------------
 
   
2. In fact, the Company has stated in certain of its pleadings in the litigation
   described in the Consent Solicitation Statement under the caption 'CERTAIN
   LEGAL PROCEEDINGS' that 'Tesoro has taken steps to reduce debt service by
   redeeming $34.6 million of 12 3/4% Subordinated Debentures effected December
   1, 1995, thus satisfying the balance of Tesoro's sinking fund requirements.

   Tesoro management has considered other possible restructuring scenarios, but
   believes, as it has advised the public in its March 31, 1995 First Quarter
   report [on Form 10-Q], that it would not be prudent to undertake refinancing
   prior to resolution of the Tennessee Gas litigation, since it would not
   result in any short-term savings given the significant cost of any
   refinancing, additional restrictions that would be required and the Company's
   credit rating, which continues to be adversely affected by the Tennessee Gas
   litigation.' Additionally, the Company also stated that the Committee has not
   disclosed how it proposes to effect such refinancing or on what terms.
   'Although the [Committee] states that a divestiture of the refining business,
   if it took the form of a sale, would produce proceeds that 'could be used to
   reduce the Company's high-cost debt,' this statement lacks any credible basis
   . . . . [A] 'fire sale' of Tesoro's refinery business, which is what the
   Committee says it expects to attempt, would at current market prices actually
   destroy shareholder value, by wiping out any value gained by strategic
   improvements in refinery operations--improvements that will become readily
   apparent to all (including potential buyers) when the Company's initiatives
   are fully implemented and industry conditions improve. The Committee also
   fails to disclose that opportunities exist in today's depressed industry
   environment, such as by consolidating the Company's refining and marketing
   assets with other existing operations, thereby creating operating synergies
   and enhancing the attractiveness of that segment of the Company's business to
   (and the price that could be realized from) a prospective purchaser. As far
   as paying down high-cost debt with sales proceeds is concerned, what the
   Committee fails to disclose is that, as discussed above, the proceeds from a
   sale in today's market, net of environmental costs and other liabilities
   related to the refinery, would be virtually non-existent, and that Tesoro's
   current credit agreement would, in all likelihood, preclude such a sale.'

                    THE COMMITTEE NOMINEES ARE COMMITTED TO
                   REORGANIZING AND REVITALIZING THE COMPANY
 
     The Committee Nominees will be flexible in pursuing the goal of maximizing
stockholder value. They are prepared to tailor the steps outlined above to the
extent they believe desirable to better suit the Company's situation, and will
fully evaluate alternatives to those steps, such as a sale of the entire
Company. They will, of course, be open to the views and suggestions of
stockholders.
 
   
     The Committee has not had discussions with potential acquirors of the
Refining Business, any of the Company's other assets or the Company as a whole.
However, in May of 1995, Kevin S. Flannery, a member of the Committee, acting on
his own and without any authority from the Company, attempted to sell all of the
Company and/or part of its E & P Business. Although he approached as many
potential acquirors as he could identify, he had no success. Mr. Flannery,
however, did not attempt to sell the Refinery Business by itself. In May of
1995, it was Mr. Flannery's expectation that, to the extent he was instrumental
in arranging for the sale of some or all of the Company, he would seek a fee for
those services. At the present time, Mr. Flannery has no agreement, arrangement
or understanding concerning his role in any sale of the Company or some or all

of its assets. Additionally, the Committee Nominees have not considered whether,
if elected, to cause the Company to enter into any agreement with Mr. Flannery
to engage his services in connection with the sale of the Refining Business, or
any other assets or businesses of the Company. To the extent that Mr. Flannery
were asked to play such a role and perform services in connection therewith, he
would expect to be compensated in a commercially reasonable manner. To the
extent Mr. Flannery were to receive a fee for such services, he might be deemed
to have a conflict of interest with all other stockholders who would not share
in such a fee. There can be no assurance that, if elected, the Committee
Nominees will be able to accomplish the disposition of the Refining Business or
other assets, or as to the timing of or amount of proceeds from any such
disposition which may be arranged. Moreover, while we think that a disposition
of the Refining Business and the use of all or part of any sale proceeds to
reduce debt or the other steps to be considered will have a favorable impact on
stockholder value, the trading price of the Common Stock is, of course,
influenced by many factors and, therefore, it is impossible to say with
certainty that its price will increase or to predict the amount of any such
increase that might occur. We think, though, that vigorous and concentrated
efforts to enhance the value of your investments in the Company should be made.
    
 
   
     Except as described above, the Committee and the Committee Nominees have no
present plans or proposals which relate to or would result in an extraordinary
corporate transaction, such as a merger, reorganization, liquidation, relocation
of operations or sale or transfer of assets involving the Company or any of its
subsidiaries, or any material changes in the Company's business, corporate
structure or policies; however, as stated above, the Committee Nominees, if
elected, intend to consider all of these alternatives. In the event such a
transaction materializes, stockholders will have the opportunity to vote thereon
to the extent required by law and the Company's Amended and Restated Certificate
of Incorporation.

                       HELP US MAXIMIZE STOCKHOLDER VALUE
 
     THE BASIC ISSUE WE ARE RAISING THROUGH THIS CONSENT SOLICITATION IS WHETHER
THE INCUMBENT DIRECTORS' RECORD JUSTIFIES THEIR CONTINUATION IN OFFICE OR
WHETHER A NEW BOARD OF DIRECTORS SHOULD BE GIVEN THE OPPORTUNITY TO SEEK NEW
DIRECTIONS FOR THE BENEFIT OF ALL STOCKHOLDERS OF THE COMPANY.
 
     We believe that many of you share our discontent and concerns. In order to
address those concerns, the Committee seeks your help to remove the directors
now in office and elect five new directors who, we believe, will be responsive
to stockholders and firmly committed to the goal of increasing stockholder
value.
 
     Your consent is important. No matter how many or how few shares you own,
please help us to improve stockholder value by completing, signing, dating and
mailing the enclosed WHITE Consent Card promptly.
 
     YOU ARE URGED TO CONSENT TO THE REMOVAL OF THE BOARD AND THE ELECTION OF

THE COMMITTEE NOMINEES BY MARKING, SIGNING, DATING, AND RETURNING PROMPTLY THE
ENCLOSED WHITE CONSENT CARD IN THE POSTAGE-PAID ENVELOPE PROVIDED. FAILURE TO
EXECUTE A CONSENT WILL HAVE THE SAME EFFECT AS WITHHOLDING A CONSENT.
 
     THE COMMITTEE URGES YOU NOT TO SIGN ANY GREEN REVOCATION OF CONSENT CARDS
SENT TO YOU BY THE COMPANY. IF YOU HAVE PREVIOUSLY SIGNED A GREEN REVOCATION OF
CONSENT CARD, YOU HAVE EVERY REASON TO CHANGE YOUR MIND AND MAY DO SO BY
MARKING, SIGNING, DATING AND RETURNING A LATER-DATED WHITE CONSENT CARD.
 
     If your shares of Common Stock are held in the name of a brokerage firm,
bank nominee or other institution, only it can execute a Consent Card with
respect to your shares. Accordingly, please contact the person responsible for
your account and give instructions for a WHITE Consent Card to be signed
representing your shares. The Committee requests that you confirm your
instructions to the person responsible for your account in writing and provide a
copy of such instructions to the Committee c/o Morrow & Co., Inc., 909 Third
Avenue, New York, New York 10022 so that the Committee will be aware of all
instructions given and can attempt to ensure that such instructions are
followed.
 
     If you have any questions about completing or signing the Consent Card or
require assistance, including assistance in assuring that any of your shares
held by brokers or other nominees are voted, please call Morrow & Co., Inc. at
(800) 634-4458.
 
                                          Very truly yours,

                                          /s/ Kevin S. Flannery
                                          Kevin S. Flannery, on behalf of
                                          The Stockholders' Committee for
                                          New Management of Tesoro Petroleum
