     The undersigned acknowledges that he or she has received the Prospectus,
dated           , 1998 (the "Prospectus") of Tesoro Petroleum Corporation, a
Delaware corporation (the "Company"), and this Letter of Transmittal and the
instructions hereto (the "Letter of Transmittal"), which together constitute the
Company's offer (the "Exchange Offer") to exchange $1,000 principal amount of
its 9% Senior Subordinated Notes due 2008, Series B (the "Exchange Notes") that
have been registered under the Securities Act of 1933, as amended (the
"Securities Act"), pursuant to a Registration Statement of which the Prospectus
is a part, for each $1,000 principal amount of its outstanding 9% Senior
Subordinated Notes due 2008, (the "Old Notes"), of which $300,000,000 aggregate
principal amount is outstanding, upon the terms and subject to the conditions
set forth in the Prospectus. The term "Expiration Date" shall mean 5:00 p.m.,
New York City time, on           , 1998, unless the Company, in its sole
discretion, extends the Exchange Offer, in which case the term shall mean the

Exchange Agent.

are registered on the books of the Company or any other person who has obtained
a properly completed bond power from the registered holder.

tendering described in the Instructions to this Letter of Transmittal. Holders
of Old Notes whose certificates are not immediately available, or who are unable
to deliver their certificates or Book-Entry Confirmation and all other documents
required by this Letter of Transmittal to be delivered to the Exchange Agent on
or prior to the Expiration Date, must tender their Old Notes according to the
guaranteed delivery procedures set forth under the caption "The Exchange
Offer -- Guaranteed Delivery Procedures" in the Prospectus. (See Instruction 2.)
 
     Upon the terms and subject to the conditions of the Exchange Offer, the
acceptance for exchange of the Old Notes validly tendered and not withdrawn and
the issuance of the Exchange Notes will be made promptly following the
Expiration Date. For the purposes of the Exchange Offer, the Company shall be
deemed to have accepted for exchange validly tendered Old Notes when, as and if
the Company has given written notice thereof to the Exchange Agent.
 
     The undersigned has completed, executed and delivered this Letter of
Transmittal to indicate the action the undersigned desires to take with respect
to the Exchange Offer. Holders who wish to tender their Old Notes must complete

     If the undersigned is not a broker-dealer, the undersigned represents that
it is not engaged in, and does not intend to engage in, a distribution of
Exchange Notes. If the undersigned is a broker-dealer that will receive Exchange
Notes for its own account in exchange for Old Notes that were acquired as a
result of market-making activities or other trading activities, it acknowledges
that it will deliver a prospectus in connection with any resale of such Exchange
Notes; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
 
                    NOTE: SIGNATURES MUST BE PROVIDED BELOW
                PLEASE READ ACCOMPANYING INSTRUCTIONS CAREFULLY
 
Ladies and Gentlemen:
 
     Subject to the terms and conditions of the Exchange Offer, the undersigned
hereby tenders to Tesoro Petroleum Corporation (the "Company") the principal
amount of Old Notes indicated above.
 
     Subject to and effective upon the acceptance for exchange of the principal
amount of Old Notes tendered hereby in accordance with this Letter of
Transmittal, the undersigned sells, assigns and transfers to, or upon the order
of, the Company all right, title and interest in and to the Old Notes tendered
hereby. The undersigned hereby irrevocably constitutes and appoints the Exchange
Agent as its agent and attorney-in-fact (with full knowledge that the Exchange
Agent also acts as the agent of the Company and as Trustee and Registrar under
the Indenture for the Old Notes and the Exchange Notes) with respect to the
tendered Old Notes with full power of substitution (such power of attorney being
deemed an Irrevocable power coupled with an interest), subject only to the right
of withdrawal described in the Prospectus, to (i) deliver certificates for such
Old Notes to the Company or transfer ownership of such Old Notes on the account
books maintained by DTC, together, in either such case, with all accompanying
evidences of transfer and authenticity to, or upon the order of, the Company and
(ii) present such Old Notes for transfer on the books of the Company and receive
all benefits and otherwise exercise all rights of beneficial ownership of such
Old Notes, all in accordance with the terms of the Exchange Offer.
 
     The undersigned acknowledges that the Exchange Offer is being made in
reliance upon interpretative advice given by the staff of the Securities and
Exchange Commission to third parties in connection with
                                        5
   6
 
transactions similar to the Exchange Offer, so that the Exchange Notes issued
pursuant to the Exchange Offer in exchange for the Old Notes may be offered for
resale, resold and otherwise transferred by holders thereof (other than a
broker-dealer who purchased such Old Notes directly from the Company for resale
pursuant to Rule 144A or any other available exemption under the Securities Act
or a person that is an "affiliate" of the Company or any Guarantor within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such Exchange Notes are acquired in the ordinary course of such holders'
business and such holders have no arrangement with any person to participate in
the distribution of such Exchange Notes.
 
     The undersigned agrees that acceptance of any tendered Old Notes by the
Company and the issuance of Exchange Notes in exchange therefor shall constitute
performance in full by the Company of its obligations under the Registration
Rights Agreement, (as defined in the Prospectus) and that, upon the issuance of
the Exchange Notes, the Company will have no further obligations or liabilities
thereunder (except in certain limited circumstances).
 
     The undersigned represents and warrants that (i) the Exchange Notes
acquired pursuant to the Exchange Offer are being acquired in the ordinary
course of business of the person receiving Exchange Notes (which shall be the
undersigned unless otherwise indicated in the box entitled "Special Delivery
Instructions" above) (the "Recipient"), (ii) neither the undersigned nor the
Recipient (if different) is engaged in, intends to engage in or has any
arrangement or understanding with any person to participate in the distribution
of such Exchange Notes and (iii) neither the undersigned nor the Recipient (if
different) is an "affiliate" of the Company or any Guarantor as defined in Rule
405 under the Securities Act. If the undersigned is not a broker-dealer, the
undersigned further represents that it is not engaged in, and does not intend to
engage in, a distribution of the Exchange Notes. If the undersigned is a
broker-dealer, the undersigned further (x) represents that it acquired Old Notes
for the undersigned's own account as a result of market making activities or
other trading activities, (y) represents that it has not entered into any
arrangement or understanding with the Company or any "affiliate" of the Company
(within the meaning of Rule 405 under the Securities Act) to distribute the
Exchange Notes to be received in the Exchange Offer and (z) acknowledges that it
will deliver a prospectus meeting the requirements of the Securities Act (for
which purposes delivery of the Prospectus, as the same may be hereafter
supplemented or amended, shall be sufficient) in connection with any resale of
Exchange Notes received in the Exchange Offer. Such a broker-dealer will not be
deemed, solely by reason of such acknowledgment and prospectus delivery, to
admit that it is an "underwriter" within the meaning of the Securities Act.
 
     The undersigned understands and agrees that the Company reserves the right
not to accept tendered Old Notes from any tendering holder if the Company
determines, in its sole and absolute discretion, that such acceptance could
result in a violation of applicable securities laws.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, exchange, assign and transfer the Old Notes
tendered hereby and to acquire Exchange Notes issuable upon the exchange of such
tendered Old Notes, and that, when the same are accepted for exchange, the
Company will acquire good and unencumbered title thereto, free and clear of all
liens, restrictions, charges and encumbrances and not subject to any adverse
claim. The undersigned also warrants that it will, upon request, execute and
deliver any additional documents deemed to be necessary or desirable by the
Exchange Agent or the Company in order to complete the exchange, assignment and
transfer of tendered Old Notes or transfer of ownership of such Old Notes on the
account books maintained by a book-entry transfer facility.
 
     The undersigned understands and acknowledges that the Company reserves the
right in its sole discretion to purchase or make offers for any Old Notes that
remain outstanding subsequent to the Expiration Date or, as set forth in the
Prospectus under the caption "The Exchange Offer -- Procedures for Tendering,"
to terminate the Exchange Offer and, to the extent permitted by applicable law,
purchase Old Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers could differ from the terms
of the Exchange Offer.
 
     The undersigned understands that the Company may accept the undersigned's
tender by delivering notice of acceptance, as provided below, to the Exchange
Agent, at which time the undersigned's right to withdraw
                                        6
   7
 
such tender will terminate. For purposes of the Exchange Offer, the Company
shall be deemed to have accepted validly tendered Old Notes when, as and if the
Company has given oral (which shall be confirmed in writing) or written notice
thereof to the Exchange Agent.
 
     The undersigned understands that the first interest payment following the
Expiration Date will include unpaid interest on the Old Notes accrued through
the date of issuance of the Exchange Notes.
 
     The undersigned understands that tenders of Old Notes pursuant to the
procedures described under the caption "The Exchange Offer -- Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding agreement between the undersigned and the Company upon the terms and
subject to the conditions of the Exchange Offer.
 
     The undersigned acknowledges that the Exchange Offer is subject to the more
detailed terms set forth in the Prospectus and, in case of any conflict between
the terms of the Prospectus and this Letter of Transmittal, the Prospectus shall
prevail.
 
     If any tendered Old Notes are not accepted for exchange pursuant to the
Exchange Offer for any reason, certificates for any such unaccepted Old Notes
will be returned (except as noted below with respect to tenders through DTC) at
the Company's cost and expense, to the undersigned at the address shown below or
at a different address as may be indicated herein under "Special Delivery
Instructions" as promptly as practicable after the Expiration Date.
 
     All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the undersigned's heirs, personal
representatives, successors and assigns. This tender may be withdrawn only in
accordance with the procedures set forth in this Letter of Transmittal.
 
     By acceptance of the Exchange Offer, each broker-dealer that receives
Exchange Notes pursuant to the Exchange Offer hereby acknowledges and agrees
that upon the receipt of notice by the Company of the happening of any event
which makes any statement in the Prospectus untrue in any material respect or
which requires the making of any changes in the Prospectus in order to make the
statements therein not misleading (which notice the Company agrees to deliver
promptly to such broker-dealer), such broker-dealer will suspend use of the
Prospectus until the Company has amended or supplemented the Prospectus to
correct such misstatement or omission and has furnished copies of the amended or
supplemented prospectus to such broker-dealer.
 
     Unless otherwise indicated under "Special Registration Instructions,"
please issue the certificates representing the Exchange Notes issued in exchange
for the Old Notes accepted for exchange and return any certificates for Old
Notes not tendered or not exchanged, in the name(s) of the undersigned (or, in
either such event in the case of Old Notes tendered by DTC, by credit to the
account at DTC). Similarly, unless otherwise indicated under "Special Delivery
Instructions," please send the certificates representing the Exchange Notes
issued in exchange for the Old Notes accepted for exchange and return any
certificates for Old Notes not tendered or not exchanged (and accompanying
documents, as appropriate) to the undersigned at the address shown below the
undersigned's signature(s), unless, in either event, tender is being made
through DTC. In the event that both "Special Registration Instructions" and
"Special Delivery Instructions" are completed, please issue the certificates
representing the Exchange Notes issued in exchange for the Old Notes accepted
for exchange in the name(s) of, and return any certificates for Old Notes not
tendered or not exchanged to, the person(s) so indicated. The undersigned
understands that the Company has no obligations pursuant to the "Special
Registration Instructions" or "Special Delivery Instructions" to transfer any
Old Notes from the name of the registered Holder(s) thereof if the Company does
not accept for exchange any of the Old Notes so tendered.
 
     Holders who wish to tender the Old Notes and (i) whose Old Notes are not
immediately available or (ii) who cannot deliver their Old Notes, this Letter of
Transmittal or any other documents required hereby to the Exchange Agent prior
to the Expiration Date, may tender their Old Notes according to the guaranteed
delivery procedures set forth in the Prospectus under the caption "The Exchange
Offer -- Guaranteed Delivery Procedures." See Instruction 1 regarding the

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
 
     1. Guarantee of Signatures. Signatures on this Letter of Transmittal need
not be guaranteed if (a) this Letter of Transmittal is signed by the registered
holder(s) of the Old Notes tendered herewith and such holder(s) have not
completed the box set forth herein entitled "Special Registration Instructions"
or the box entitled "Special Delivery Instructions" or (b) such Old Notes are
tendered for the account of an Eligible Institution. (See Instruction 6.)
Otherwise, all signatures on this Letter of Transmittal or a notice of
withdrawal, as the case may be, must be guaranteed by a member firm of a
registered national securities exchange or of the National Association of
Securities Dealers, Inc. or a commercial bank or trust company having an office
or correspondent in the United States (an "Eligible Institution"). All
signatures on bond powers and endorsements on certificates must also be
guaranteed by an Eligible Institution.
 
     2. Delivery of this Letter of Transmittal and Old Notes. Certificates for
all physically delivered Old Notes or confirmation of any book-entry transfer to
the Exchange Agent at DTC of Old Notes tendered by book-entry transfer, as well
as, in each case (including cases where tender is affected by book-entry
transfer), a properly completed and duly executed copy of this Letter of
Transmittal or facsimile hereof and any other documents required by this Letter
of Transmittal must be received by the Exchange Agent at its address set forth
herein prior to 5:00 p.m., New York City time, on the Expiration Date.
 
     The method of delivery of the tendered Old Notes, this Letter of
Transmittal and all other required documents to the Exchange Agent is at the
election and risk of the Holder and the delivery will be deemed made only when
actually received by the Exchange Agent. If Old Notes are sent by mail,
certified or registered mail with return receipt requested, properly insured, is
recommended. In all cases, sufficient time should be allowed to ensure timely
delivery. No Letter of Transmittal or Old Notes should be sent to the Company.
 
     The Exchange Agent will make a request to establish an account with respect
to the Old Notes at the Depositary for purposes of the Exchange Offer within two
business days after receipt of this Prospectus, and
 
                                        9
   10
 
any financial institution that is a participant in the Depositary may make
book-entry delivery of Old Notes by causing the Depositary to transfer such Old
Notes into the Exchange Agent's account at the Depositary in accordance with the
Depositary's procedures for transfer. However, although delivery of Old Notes
may be effected through book-entry transfer at the Depositary, the Letter of
Transmittal, with any required signature guarantees or an Agent's Message (as
defined below) in connection with a book-entry transfer and any other required
documents, must, in any case, be transmitted to and received by the Exchange
Agent at the address specified on the cover page of the Letter of Transmittal on
or prior to the Expiration Date or the guaranteed delivery procedures described
below must be complied with.
 
     A Holder may tender Old Notes that are held through the Depositary by
transmitting its acceptance through the Depositary's Automatic Tender Offer
Program, for which the transaction will be eligible, and the Depositary will
then edit and verify the acceptance and send an Agent's Message to the Exchange
Agent for its acceptance. The term "Agent's Message" means a message transmitted
by the Depositary to, and received by, the Exchange Agent and forming part of
the Book-Entry Confirmation, which states that the Depositary has received an
express acknowledgment from each participant in the Depositary tendering the Old
Notes and that such participant has received the Letter of Transmittal and
agrees to be bound by the terms of the Letter of Transmittal and the Company may
enforce such agreement against such participant.
 
     Holders who wish to tender their Old Notes and (i) whose Old Notes are not
immediately available, or (ii) who cannot deliver their Old Notes, this Letter
of Transmittal or any other documents required hereby to the Exchange Agent
prior to the Expiration Date or comply with book-entry transfer procedures on a
timely basis must tender their Old Notes according to the guaranteed delivery
procedures set forth in the Prospectus. See "Exchange Offer -- Guaranteed
Delivery Procedures." Pursuant to such procedure: (i) such tender must be made
by or through an Eligible Institution; (ii) prior to the Expiration Date, the
Exchange Agent must have received from the Eligible Institution a properly
completed and duly executed Notice of Guaranteed Delivery (by facsimile
transmission, overnight courier, mail or hand delivery) setting forth the name
and address of the Holder of the Old Notes, the certificate number or numbers of
such Old Notes and the principal amount of Old Notes tendered, stating that the
tender is being made thereby and guaranteeing that, within three New York Stock
Exchange trading days after the Expiration Date, this Letter of Transmittal (or
facsimile hereof) together with the certificate(s) representing the Old Notes
and any other required documents will be deposited by the Eligible Institution
with the Exchange Agent; and (iii) such properly completed and executed Letter
of Transmittal (or facsimile hereof), as well as all other documents required by
this Letter of Transmittal and the certificate(s) representing all tendered Old
Notes in proper form for transfer (or a confirmation of book-entry transfer of
such Old Notes into the Exchange Agent's account at DTC), must be received by
the Exchange Agent within three New York Stock Exchange trading days after the
Expiration Date, all in the manner provided in the Prospectus under the caption
"The Exchange Offer -- Guaranteed Delivery Procedures." Any Holder who wishes to
tender his Old Notes pursuant to the guaranteed delivery procedures described
above must ensure that the Exchange Agent receives the Notice of Guaranteed
Delivery prior to 5:00 p.m., New York City time, on the Expiration Date. Upon
request to the Exchange Agent, a Notice of Guaranteed Delivery will be sent to
Holders who wish to tender their Old Notes according to the guaranteed delivery
procedures set forth above.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes, and withdrawal of tendered Old Notes
will be determined by the Company in its sole discretion, which determination
will be final and binding. All tendering holders, by execution of this Letter of
Transmittal (or facsimile thereof), shall waive any right to receive notice of
the acceptance of the Old Notes for exchange. The Company reserves the absolute
right to reject any and all Old Notes not properly tendered or any Old Notes the
Company's acceptance of which would, in the opinion of counsel for the Company,
be unlawful. The Company also reserves the right to waive any irregularities or
conditions of tender as to particular Old Notes. The Company's interpretation of
the terms and conditions of the Exchange Offer (including the instructions in
this Letter of Transmittal) shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Old Notes
must be cured within such time as the Company shall determine. Neither the
Company, the Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of Old Notes,
nor shall any of them incur any
 
                                       10
   11
 
liability for failure to give such notification. Tenders of Old Notes will not
be deemed to have been made until such defects or irregularities have been cured
to the Company's satisfaction or waived. Any Old Notes received by the Exchange
Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering Holders pursuant to the Company's determination, unless
otherwise provided in this Letter of Transmittal as soon as practicable
following the Expiration Date. The Exchange Agent has no fiduciary duties to the
Holders with respect to the Exchange Offer and is acting solely on the basis of
directions of the Company.
 
     3. Inadequate Space. If the space provided is inadequate, the certificate
numbers and/or the number of Old Notes should be listed on a separate signed
schedule attached hereto.
 
     4. Tender by Holder. Only a Holder of Old Notes may tender such Old Notes
in the Exchange Offer. Any beneficial owner of Old Notes who is not the
registered Holder and who wishes to tender should arrange with such registered
holder to execute and deliver this Letter of Transmittal on such beneficial
owner's behalf or must, prior to completing and executing this Letter of
Transmittal and delivering his Old Notes, either make appropriate arrangements
to register ownership of the Old Notes in such beneficial owner's name or obtain
a properly completed bond power from the registered holder or properly endorsed
certificates representing such Old Notes.
 
     5. Partial Tenders; Withdrawals. Tenders of Old Notes will be accepted only
in integral multiples of $1,000. If less than the entire principal amount of any
Old Notes is tendered, the tendering Holder should fill in the principal amount
tendered in the third column of the box entitled "Description of 9% Senior
Subordinated Notes due 2008" above. The entire principal amount of any Old Notes
delivered to the Exchange Agent will be deemed to have been tendered unless
otherwise indicated. If the entire principal amount of all Old Notes is not
tendered, then Old Notes for the principal amount of Old Notes not tendered and
a certificate or certificates representing Exchange Notes issued in exchange for
any Old Notes accepted will be sent to the Holder at his or her registered
address, unless a different address is provided in the "Special Delivery
Instructions" box above on this Letter of Transmittal or unless tender is made
through DTC, promptly after the Old Notes are accepted for exchange.
 
     Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the Expiration Date. To
withdraw a tender of Old Notes in the Exchange Offer, a written or facsimile
transmission notice of withdrawal must be received by the Exchange Agent at its
address set forth herein prior to 5:00 p.m., New York City time, on the
Expiration Date. Any such notice of withdrawal must (i) specify the name of the
person having deposited the Old Notes to be withdrawn (the "Depositor"), (ii)
identify the Old Notes to be withdrawn (including the certificate number or
numbers and principal amount of such Old Notes, or, in the case of Old Notes
transferred by book-entry transfer the name and number of the account at DTC to
be credited), (iii) be signed by the Depositor in the same manner as the
original signature on the Letter of Transmittal by which such Old Notes were
tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Registrar, with respect to the Old
Notes, register the transfer of such Old Notes into the name of the person
withdrawing the tender and (iv) specify the name in which any such Old Notes are
to be registered, if different from that of the Depositor. All questions as to
the validity, form and eligibility (including time of receipt) of such notices
will be determined by the Company, whose determination shall be final and
binding on all parties. Any Old Notes so withdrawn will be deemed not to have
been validly tendered for purposes of the Exchange Offer and no Exchange Notes
will be issued with respect thereto unless the Old Notes so withdrawn are
validly retendered. Any Old Notes which have been tendered but which are not
accepted for exchange by the Company will be returned to the Holder thereof
without cost to such Holder as soon as practicable after withdrawal, rejection
of tender or termination of the Exchange Offer. Properly withdrawn Old Notes may
be retendered by following one of the procedures described in the Prospectus
under "The Exchange Offer -- Procedures for Tendering" at any time prior to the
Expiration Date.
 
     6. Signatures on the Letter of Transmittal; Bond Powers and
Endorsements. If this Letter of Transmittal (or facsimile hereof) is signed by
the registered holder(s) of the Old Notes tendered hereby, the signature
 
                                       11
   12
 
must correspond with the name(s) as written on the face of the Old Note without
alteration, enlargement or any change whatsoever.
 
     If any of the Old Notes tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.
 
     If a number of Old Notes registered in different names are tendered, it
will be necessary to complete, sign and submit as many copies of this Letter of
Transmittal as there are different registrations of Old Notes.
 
     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder or Holders (which term, for the purposes described herein,
shall include a book-entry transfer facility whose name appears on a security
listing as the owner of the Old Notes) of Old Notes tendered and the certificate
or certificates for Exchange Notes issued in exchange therefor is to be issued
(or any untendered principal amount of Old Notes to be reissued) to the
registered Holder, then such Holder need not and should not endorse any tendered
Old Notes, nor provide a separate bond power. In any other case, such Holder
must either properly endorse the Old Notes tendered or transmit a properly
completed separate bond power with this Letter of Transmittal with the
signatures on the endorsement or bond power guaranteed by an Eligible
Institution.
 
     If this Letter of Transmittal (or facsimile hereof) is signed by a person
other than the registered Holder or Holders of any Old Notes listed, such Old
Notes must be endorsed or accompanied by appropriate bond powers in each case
signed as the name of the registered Holder or Holders appears on the Old Notes.
 
     If this Letter of Transmittal (or facsimile hereof) or any Old Notes or
bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, or officers of corporations or others acting in a fiduciary
or representative capacity, such persons should so indicate when signing, and
unless waived by the Company, evidence satisfactory to the Company of their
authority so to act must be submitted with this Letter of Transmittal.
 
     Endorsements on Old Notes or signatures on bond powers required by this
Instruction 6 must be guaranteed by an Eligible Institution.
 
     7. Special Registration and Delivery Instructions. Tendering Holders should
indicate, in the applicable box or boxes, the name and address to which Exchange
Notes or substitute Old Notes for principal amounts not tendered or not accepted
for exchange are to be issued or sent, if different from the name and address of
the person signing this Letter of Transmittal. In the case of issuance in a
different name, the taxpayer identification or social security number of the
person named must also be indicated.
 
     8. Backup Federal Income Tax Withholding and Substitute Form W-9. Under the
federal income tax laws, payments that may be made by the Company on account of
Exchange Notes issued pursuant to the Exchange Offer may be subject to backup
withholding at the rate of 31%. In order to avoid such backup withholding, each
tendering Holder should complete and sign the Substitute Form W-9 included in
this Letter of Transmittal and either (a) provide the correct taxpayer
identification number ("TIN") and certify, under penalties of perjury, that the
TIN provided is correct and that (i) the Holder has not been notified by the
Internal Revenue Service (the "IRS") that the Holder is subject to backup
withholding as a result of failure to report all interest or dividends or (ii)
the IRS has notified the Holder that the Holder is no longer subject to backup
withholding; or (b) provide an adequate basis for exemption. If the tendering
Holder has not been issued a TIN and has applied for one, or intends to apply
for one in the near future, such Holder should write "Applied For" in the space
provided for the TIN in Part I of the Substitute Form W-9, sign and date the
Substitute Form W-9 and sign the Certificate of Payee Awaiting Taxpayer
Identification Number. If "Applied For" is written in Part 1, notwithstanding
that the Certificate of Payee Awaiting Taxpayer Identification Number is
completed, the Company (or the Paying Agent under the Indenture governing the
Exchange Notes) shall withhold 31% of payments made to the tendering Holder
seven days following receipt by the Company or Paying Agent of the Certificate
of Payee Awaiting Taxpayer Identification Number and prior to the time a
properly certified TIN is provided to the Company or Paying Agent. In general,
if a Holder is an individual, the TIN is the Social Security number of such
individual. If the Exchange Agent or the Company are not provided with the
correct TIN, the Holder may be subject to a $50 penalty imposed by the Internal
Revenue Service. Certain Holders (including, among others, all corporations and
certain foreign persons) are
                                       12
   13
 
not subject to these backup withholding and reporting requirements. In order for
a foreign person to qualify as an exempt recipient, such Holder must submit a
statement (generally, IRS Form W-8), signed under penalties of perjury,
attesting to that person's exempt status. Such statements can be obtained from
the Exchange Agent. For further information concerning backup withholding and
instructions for completing the Substitute Form W-9 (including how to obtain a
taxpayer identification number if you do not have one and how to complete the
Substitute Form W-9 if Old Notes are registered in more than one name), consult
the enclosed Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9.
 
     Failure to complete the Substitute Form W-9 will not, by itself, cause Old
Notes to be deemed invalidly tendered, but may require the Company (or the
Paying Agent) to withhold 31% of the amount of any payments made on account of
the Exchange Notes. Backup withholding is not an additional federal income tax.
Rather, the federal income tax liability of a person subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, the Holder may apply for a refund from the
IRS.
 
     9. Transfer Taxes. The Company will pay all transfer taxes, if any,
applicable to the exchange of Old Notes pursuant to the Exchange Offer. If,
however, certificates representing Exchange Notes or Old Notes for principal
amounts not tendered or accepted for exchange are to be delivered to, or are to
be registered in the name of, any person other than the registered holder of the
Old Notes tendered hereby, or if tendered Old Notes are registered in the name
of a person other than the person signing this Letter of Transmittal, or if a
transfer tax is imposed for any reason other than the exchange of Old Notes
pursuant to the Exchange Offer, then the amount of any such transfer taxes
(whether imposed on the registered holder or on any other persons) will be
payable by the tendering Holder. If satisfactory evidence of payment of such
taxes or exemption therefrom is not submitted with this Letter of Transmittal,
the amount of such transfer taxes will be billed directly to such tendering
Holder. See the Prospectus under "The Exchange Offer -- Solicitation of Tenders;
Fees and Expenses."
 
     Except as provided in this Instruction 9, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes listed in this Letter of
Transmittal.
 
     10. Waiver of Conditions. The Company reserves the right, in its sole
discretion, to amend, waive or modify specified conditions in the Exchange Offer
in the case of any Old Notes tendered.
 
     11. Mutilated, Lost, Stolen or Destroyed Old Notes. Any tendering Holder
whose Old Notes have been mutilated, lost, stolen or destroyed should contact
the Exchange Agent at the address indicated herein for further instructions.
 
     12. Requests for Assistance or Additional Copies. Requests for assistance
and requests for additional copies of the Prospectus or this Letter of
Transmittal may be directed to the Exchange Agent at the address specified in
the Prospectus. Holders may also contact their broker, dealer, commercial bank,
trust company or other nominee for assistance concerning the Exchange Offer.

                           IMPORTANT TAX INFORMATION
 
     Under federal income tax laws, a Holder whose tendered Old Notes are
accepted for exchange is required to provide the Company or the Paying Agent (as
payer) with such Holder's correct TIN on Substitute
 
                                       13
   14
 
Form W-9 below or otherwise establish a basis for exemption from backup
withholding. If such Holder is an individual, the TIN is his or her social
security number. If the Company or the Paying Agent is not provided with the
correct TIN, a $50 penalty may be imposed by the Internal Revenue Service, and
payments made on Exchange Notes issued pursuant to the Exchange Offer may be
subject to backup withholding.
 
     Certain Holders (including, among others, all corporations and certain
foreign persons) are not subject to these backup withholding and reporting
requirements. Exempt Holders should indicate their exempt status on Substitute
Form W-9. A foreign person may qualify as an exempt recipient by submitting to
the Exchange Agent a properly completed Internal Revenue Service Form W-8,
signed under penalties of perjury, attesting to that Holder's exempt status. A
Form W-8 can be obtained from the Exchange Agent. See the enclosed "Guidelines
for Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional instructions.
 
     If backup withholding applies, the Company or the Paying Agent is required
to withhold 31% of any payments made to the Holder or other payee. Backup
withholding is not an additional federal income tax. Rather, the federal income
tax liability of persons subject to backup withholding will be reduced by the
amount of tax withheld. If withholding results in an overpayment of taxes, a
refund may be applied for with the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
     To prevent backup withholding on payments made on Exchange Notes issued
pursuant to the Exchange Offer, the Holder is required to provide the Exchange
Agent with either: (i) the Holder's correct TIN by completing the form below,
certifying that the TIN provided on Substitute Form W-9 is correct (or that such
Holder is awaiting a TIN) and that (A) the Holder has not been notified by the
Internal Revenue Service that the Holder is subject to backup withholding as a
result of failure to report all interest or dividends or (B) the Internal
Revenue Service has notified the Holder that the Holder is no longer subject to
backup withholding or (ii) an adequate basis for exemption.
 
WHAT NUMBER TO GIVE THE COMPANY OR THE PAYING AGENT
 
     The Holder is required to give the Company or the Paying Agent the TIN
(e.g., social security number or employer identification number) of the
registered Holder of the Old Notes. If the Old Notes are held in more than one
name or are held not in the name of the actual owner, consult the enclosed
"Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9" for additional guidance on which number to report.
 
                                       14
   15
 
          CERTIFICATE OF PAYEE AWAITING TAXPAYER IDENTIFICATION NUMBER
 
     I certify, under penalties of perjury, that a Taxpayer Identification
Number has not been issued to me, and that I mailed or delivered an application
to receive a Taxpayer Identification Number to the appropriate Internal Revenue
Service Center or Social Security Administration Office (or I intend to mail or
deliver an application in the near future). I understand that if I do not
provide a taxpayer identification number within 60 days, 31% of all reportable
payments made to me thereafter will be withheld until I provide a number.
Moreover, I understand that during this 60-day period, 31% of all reportable
payments made to me will be withheld commencing 7 business days after the payor
receives this Certificate of Payee Awaiting Taxpayer Identification Number and
terminating on the date I provide a certified TIN to the payor.

been notified by the IRS that you are currently subject to backup withholding
because of underreporting interest or dividends on your tax return. For real
estate transactions, item 2 does not apply. However, if after being notified by
the IRS that you are currently subject to backup withholding, you received
another notification from the IRS that you are no longer subject to backup
withholding, do not cross out such item(2).

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                         NUMBER ON SUBSTITUTE FORM W-9
 
              SECTION REFERENCES ARE TO THE INTERNAL REVENUE CODE.
 
  PURPOSE OF FORM -- A person who is required to file an information return with
the IRS must obtain your correct Taxpayer Identification Number (TIN) to report
income paid to you, real estate transactions, mortgage interest you paid, the
acquisition or abandonment of secured property, cancellation of debt or
contributions you made to an IRA. Use the accompanying Substitute Form W-9 to
furnish your correct TIN to the requester (the person asking you to furnish your
TIN), and, when applicable, (1) to certify that the TIN you are furnishing is
correct (or that you are waiting for a number to be issued), (2) to certify that
you are not subject to backup withholding, or (3) to claim exemption from backup
withholding if you are an exempt payee. Furnishing your correct TIN and making
the appropriate certifications will prevent certain payments from being subject
to backup withholding.
 
  HOW TO OBTAIN A TIN. -- If you do not have a TIN, apply for one immediately.
To apply, get Form SS-5, Application for a Social Security Card (for
individuals), from your local office of the Social Security Administration, or
Form SS-4, Application for Employer Identification Number (for businesses and
all other entities), from your local IRS office.
 
  To complete Substitute Form W-9 if you do not have a TIN, write "Applied for"
in the space for the TIN in Part 1, sign and date the form, and give it to the
requester. Generally, you must obtain a TIN and furnish it to the requester by
the time of payment. If the requester does not receive your TIN by the time of
payment, backup withholding, if applicable, will begin and continue until you
furnish your TIN to the requester.
 
  Note: Writing "Applied for" on the form means that you have already applied
for a TIN OR that you intend to apply for one in the near future.
 
  As soon as you receive your TIN, complete another Substitute Form W-9, include
your TIN, sign and date the form, and give it to the requester.
 
  WHAT IS BACKUP WITHHOLDING? -- Persons making certain payments to you are
required to withhold and pay to the IRS 31% of such payments under certain
conditions. This is called "backup withholding." Payments that could be subject
to backup withholding include interest, dividends, broker and barter exchange
transactions, rents, royalties, non-employee compensation and certain payments
from fishing boat operations, but do not include real estate transactions.
 
  If you give the requester your correct TIN, make the appropriate
certifications, and report all your taxable interest and dividends on your tax
return, your payments will not be subject to backup withholding. Payments you
receive will be subject to backup withholding if:
 
1. You do not furnish your TIN to the requester, or
 
2. The IRS notifies the requester that you furnished an incorrect TIN, or
 
3. You are notified by the IRS that you are subject to backup withholding
   because you failed to report all your interest and dividends on your tax
   return (for reportable interest and dividends only), or
 
4. You do not certify to the requester that you are not subject to backup
   withholding under 3 above (for reportable interest and dividend accounts
   opened after 1983 only), or
 
5. You do not certify your TIN when required. This applies only to reportable
   interest, dividend, broker or barter exchange accounts opened after 1983,
   broker accounts considered inactive during 1983, and real estate
   transactions.
 
  Certain payees and payments are exempt from backup withholding and information
reporting. See Payees and Payments Exempt From Backup Withholding, below, and
Exempt Payees Under Specific Instructions, below, if you are an exempt payee.

make a false statement with no reasonable basis that results in no backup

certifications or affirmations may subject you to criminal penalties including

to a payee who does not furnish a TIN to a payer. Certain penalties may also
