To Depository Trust Company Participants:

     We enclose the materials listed below relating to the offer by Halliburton
Company (the "Issuer") to exchange its Senior Notes due 2005 (the "New Notes"),
the issuance of which has been registered under the Securities Act of 1933, as
amended (the "Securities Act"), for a like principal amount of its issued and
outstanding unregistered Senior Notes due 2005 (the "Outstanding Notes"), upon
the terms and subject to the conditions set forth in the Issuer's prospectus
dated           , 200 (the "Prospectus") and the related Letter of Transmittal.
The exchange of the Outstanding Notes for the New Notes and the related
documentation are referred to herein as the "Exchange Offer."

     We are enclosing copies of the following documents:

     1. Prospectus dated           , 200 ;

     2. Letter of Transmittal (together with accompanying Substitute Form W-9
        Guidelines);

     3. Notice of Guaranteed Delivery; and

     4. Letter of instructions that may be sent to your clients for whose
        account you hold Outstanding Notes in your name or in the name of your
        nominee, with space provided for obtaining such client's instructions
        with regard to the Exchange Offer.

     We urge you to contact your clients promptly. Please note that the Exchange
Offer will expire at 5:00 p.m., New York City time, on           , 200 , unless
sooner terminated or extended.

     The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Outstanding Notes being tendered for exchange.

     Pursuant to the Letter of Transmittal, each holder of Outstanding Notes
will represent to the Issuer that:

     - such person is not an "affiliate," as defined in Rule 405 under the
       Securities Act, of the Issuer or a broker-dealer tendering Outstanding
       Notes acquired directly from the Issuer for its own account;

     - if such person is not a broker-dealer, or is a broker-dealer but will not
       receive New Notes for its own account in exchange for Outstanding Notes,
       it is not engaged in, and does not intend to participate in, a
       distribution of New Notes;

     - such person does not have an arrangement or understanding with any person
       to participate in the distribution of the Outstanding Notes or the New
       Notes within the meaning of the Securities Act; and

     - any New Notes received are being acquired in the ordinary course of
       business of the person receiving such New Notes.

     If such person is a broker-dealer that will receive New Notes for its own
account in exchange for Outstanding Notes, it represents that the Outstanding
Notes to be exchanged for New Notes were acquired as a result of market-


making activities or other trading activities, and it will deliver a Prospectus
in connection with any resale of such New Notes; however, by so acknowledging
and by delivering a Prospectus, it will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

     The enclosed Letter to Clients contains an authorization by the beneficial
owners of the Outstanding Notes for you to make the foregoing representations.

     The Issuer will not pay any fee or commission to any broker or dealer or to
any other person (other than the Exchange Agent) in connection with the
solicitation of tenders of Outstanding Notes pursuant to the Exchange Offer. The
Issuer will pay or cause to be paid any transfer taxes payable on the transfer
of Outstanding Notes to it, except as otherwise provided in Instruction 7 of the
enclosed Letter of Transmittal.

     Additional copies of the enclosed material may be obtained from us or the
Exchange Agent, JPMorgan Chase Bank, upon request.
