    DELIVERY OF THIS LETTER OF TRANSMITTAL TO AN ADDRESS, OR TRANSMISSION OF
INSTRUCTIONS VIA A FACSIMILE NUMBER, OTHER THAN AS SET FORTH ABOVE, WILL NOT
CONSTITUTE A VALID DELIVERY. DELIVERIES TO THE PURCHASER, SHELL OR THE DEALER
MANAGER WILL NOT BE FORWARDED TO THE DEPOSITARY AND THEREFORE WILL NOT
CONSTITUTE VALID DELIVERY.

    THE INSTRUCTIONS ACCOMPANYING THIS LETTER OF TRANSMITTAL SHOULD BE READ
CAREFULLY BEFORE THIS LETTER OF TRANSMITTAL IS COMPLETED.

    This Letter of Transmittal is to be used if certificates for shares and/or
Rights (as defined below) are to be forwarded herewith or, unless an Agent's
Message (as defined in Section 2 of the Offer to Purchase (as defined below)) is
utilized, if delivery of shares and/or Rights is to be made by book-entry
transfer to an account maintained by the Depositary (as defined below) at the
Book-Entry Transfer Facility (as defined in Section 2 of the Offer to Purchase)
pursuant to the procedures described in Section 2 of the Offer to Purchase. See
Instruction 2. Stockholders who deliver shares and/or Rights by book-entry
transfer are referred to herein as "Book-Entry Stockholders." Stockholders whose
certificates for shares and/or Rights are not immediately available or who
cannot deliver either the certificates for, or a Book-Entry Confirmation (as
defined in Section 2 of the Offer to Purchase) with respect to, their shares
and/or Rights and all other documents required hereby to the Depositary prior to
the Expiration Date (as defined in Section 1 of the Offer to Purchase) must
tender their shares and/or Rights in accordance with the guaranteed delivery
procedures described in Section 2 of the Offer to Purchase. See Instruction 2.
DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE
DELIVERY TO THE DEPOSITARY.

    Holders of shares are required to tender one Right (as defined below) for
each share tendered to effect a valid tender of such share. Unless and until the
Distribution Date (as defined in the Offer to Purchase) occurs, the Rights are
represented by and transferred with the shares. Accordingly, if the Distribution
Date does not occur prior to the Expiration Date, a tender of shares also
constitutes a tender of the related Rights. If, however, pursuant to the Rights
Agreement (as defined below) or otherwise, the Distribution Date does occur and
separate certificates ("Rights Certificates") have been distributed by the
Company (as defined below) to holders of shares prior to the date of tender
pursuant to the Offer (as defined below), Rights
   2

Certificates representing a number of Rights equal to the number of shares being
tendered must be delivered to the Depositary in order for such shares to be
validly tendered, or if available, a Book-Entry Confirmation must be received
with respect thereto. If the Distribution Date has occurred and Rights
Certificates have not been distributed prior to the time shares are tendered
pursuant to the Offer, a tender of shares without Rights constitutes an
agreement by the tendering stockholder to deliver Rights Certificates
representing a number of Rights equal to the number of shares tendered pursuant
to the Offer to the Depositary within a period ending on the later of (1) three
trading days after the date of execution of the Notice of Guaranteed Delivery or
(2) three business days after the date such Rights Certificates are distributed.
A "trading day" is any day on which the New York Stock Exchange is open for
business. The Purchaser reserves the right to require that it receive such
Rights Certificates, or a Book-Entry Confirmation, if available, prior to
accepting shares for payment. Payment for shares tendered and purchased pursuant
to the Offer will be made only after timely receipt by the Depositary of, among
other things, Rights Certificates, if such certificates have been distributed to
holders of shares. The Purchaser will not pay any additional consideration for
the Rights tendered pursuant to the Offer.

    Holders whose certificates for shares ("Share Certificates") and, if
applicable, Rights Certificates, are not immediately available (including if the
Distribution Date has occurred but Rights Certificates have not yet been
distributed by the Company) or who cannot deliver either the certificates for,
or a Book-Entry Confirmation (as defined in the Offer to Purchase) with respect
to, their shares and/or Rights, and all other documents required hereby to the
Depositary prior to the Expiration Date must tender their shares and Rights in
accordance with the guaranteed delivery procedures set forth in Section 2 of the
Offer to Purchase. See Instruction 2.

Ladies and Gentlemen:

    The undersigned hereby tenders to SRM Acquisition Company, a Delaware
corporation (the "Purchaser") and an indirect wholly owned subsidiary of Shell
Oil Company, a Delaware corporation, (1) the above-described shares of common
stock, par value $.01 per share (the "shares"), and (2) the associated preferred
stock purchase rights (the "Rights") outstanding under the Rights Agreement (the
"Rights Agreement") dated as of August 5, 1997 by and between the Company and
BankBoston, N.A., as Rights Agent, as amended, of Barrett Resources Corporation,
a Delaware corporation (the "Company"), upon the terms and subject to the
conditions set forth in the Purchaser's Offer to Purchase dated March 12, 2001
(the "Offer to Purchase") and this Letter of Transmittal (which, together with
any amendments or supplements thereto or hereto, collectively constitute the
"Offer"), receipt of which is hereby acknowledged. Unless the context otherwise
requires, all references to shares shall be deemed to include the associated
Rights, and all references to the Rights shall be deemed to include the benefits
that may inure to holders of the Rights pursuant to the Rights Agreement.

    Upon the terms and subject to the conditions of the Offer and effective upon
acceptance for payment of and payment for the shares and Rights tendered
herewith in accordance with the terms of the Offer, the undersigned hereby
sells, assigns and transfers to, or upon the order of, the Purchaser all right,
title and interest in and to all the shares and Rights that are being tendered
hereby (and any and all other shares and Rights or other securities or rights
issued or issuable in respect thereof on or after March 12, 2001), and
irrevocably constitutes and appoints Wilmington Trust Company (the
"Depositary"), the true and lawful agent and attorney-in-fact of the
undersigned, with full power of substitution (such power of attorney being
deemed to be an irrevocable power coupled with an interest), to the full extent
of the undersigned's rights with respect to such shares and Rights (and any such
other shares and Rights or securities or rights), (1) to deliver certificates
for such shares and Rights (and any such other shares and Rights or securities
or rights) or transfer ownership of such shares and Rights (and any such other
shares and Rights or securities or rights) on the account books maintained by
the Book-Entry Transfer Facility (as defined in Section 8 of the Offer to
Purchase), together, in any such case, with all accompanying evidences of
transfer and authenticity to, or upon the order of, the Purchaser, (2) to
present such shares and Rights (and any such other shares and Rights or
securities or rights) for transfer on the Company's books and (3) to receive all
benefits and otherwise exercise all rights of beneficial ownership of such
shares and Rights (and any such other shares and Rights or securities or
rights), all in accordance with the terms of the Offer.

    The undersigned understands that, unless the Rights are redeemed prior to
the Expiration Date (as defined in Section 1 of the Offer to Purchase), holders
of shares will be required to tender one associated Right for each share
tendered in order to effect a valid tender of such share. The undersigned
understands that if the Distribution Date (as defined in Section 8 of the Offer
to Purchase) has occurred and Rights Certificates have been distributed to
holders of shares prior to the time a holder's shares are purchased pursuant to
the Offer, in order for Rights (and the corresponding shares) to be validly
tendered, Rights Certificates representing the number of Rights equal to the
number of shares tendered must be delivered to the Depositary or, if available,
a Book-Entry Confirmation must be received by the Depositary with respect
thereto. If the Distribution Date has occurred and Rights Certificates have not
been distributed prior to the time shares are purchased pursuant to the Offer,
Rights may be tendered prior to a stockholder receiving Rights Certificates by
use of the guaranteed delivery procedure described in Section 2 of the Offer to
Purchase. In any case, a tender of shares constitutes an agreement by the
tendering stockholder to deliver Rights Certificates representing a number of
Rights equal to the number of shares tendered pursuant to the Offer to the
Depositary within a period ending on the later of (1) three trading days after
the date of execution of the Notice of Guaranteed Delivery or (2) three business
days after the date Rights Certificates are distributed. A "trading day" is any
day on which the New York Stock Exchange is open for business. The Purchaser
reserves the right to require that the Depositary receive Rights Certificates,
or a Book-Entry Confirmation, if available, with respect to such Rights prior to
accepting the related shares for payment pursuant to the Offer if the
Distribution Date has occurred prior to the Expiration Date. The Purchaser will
not pay any additional consideration for the Rights tendered pursuant to the
Offer.

    If, on or after March 12, 2001, the Company should declare or pay any cash
dividend on the shares or other distribution on the shares, or issue with
respect to the shares any additional shares, shares of any other class of
capital stock, other voting securities or any securities convertible into or
exchangeable for, or rights, warrants or options, conditional or otherwise, to
acquire, any of the foregoing, payable or distributable to stockholders of
record on a date prior to the transfer of the shares purchased under the Offer
to the Purchaser or its nominee or transferee on the Company's stock transfer
records, then, subject to the provisions of Section 13 of the Offer to Purchase,
(1) the Offer price may, in the sole discretion of the Purchaser, be reduced by
the amount of any such cash dividend or cash distribution and (2) the whole of
any such noncash dividend, distribution or issuance to be received by the
tendering stockholders will (a) be received and held by the tendering
stockholders for the account of the Purchaser and will be required to be
promptly remitted and transferred by each tendering stockholder to the
Depositary for the account of the Purchaser, accompanied by appropriate
documentation of transfer, or (b) at the direction of the Purchaser, be
exercised for the benefit of the Purchaser, in which case the proceeds of that
exercise will promptly be remitted to the Purchaser. Pending such remittance and
subject to applicable law, the Purchaser will be entitled to all rights and
privileges as

                                       4
   5

owner of any such noncash dividend, distribution, issuance or proceeds and may
withhold the entire offer price or deduct from the offer price the amount or
value thereof, as determined by the Purchaser in its sole discretion.

    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the tendered shares and
Rights (and any and all other shares and Rights or other securities or rights
issued or issuable in respect of such shares and Rights on or after March 12,
2001) and, when the shares are accepted for payment by the Purchaser, the
Purchaser will acquire good title thereto, free and clear of all liens,
restrictions, claims and encumbrances, and the same will not be subject to any
adverse claim. The undersigned will, upon request, execute any additional
documents deemed by the Depositary or the Purchaser to be necessary or desirable
to complete the sale, assignment and transfer of the tendered shares (and any
and all such other shares or securities or rights).

    All authority conferred or agreed to be conferred pursuant to this Letter of
Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned and shall not be
affected by, and shall survive, the death or incapacity of the undersigned.
Except as stated in the Offer to Purchase this tender is irrevocable.

    The undersigned hereby irrevocably appoints Kenneth T. Jarvi, Brian W.
Curtis and E. Vaughn Phillips and each of them, and any other designees of the
Purchaser, the attorneys-in-fact and proxies of the undersigned, each with full
power of substitution, (1) to vote at any annual, special or adjourned meeting
of the Company's stockholders or otherwise in such manner as each such
attorney-in-fact and proxy or his substitute shall in his sole discretion deem
proper with respect to, (2) to execute any written consent concerning any matter
as each such attorney-in-fact and proxy or his substitute shall in his sole
discretion deem proper with respect to, and (3) to otherwise act as each such
attorney-in-fact and proxy or his substitute shall in his sole discretion deem
proper with respect to, the shares and Rights tendered hereby that have been
accepted for payment by the Purchaser prior to the time any such action is taken
and with respect to which the undersigned is entitled to vote (and any and all
other shares and Rights or other securities or rights issued or issuable in
respect of such shares and Rights on or after March 12, 2001). This appointment
is effective when, and only to the extent that, the Purchaser accepts for
payment such shares and Rights as provided in the Offer to Purchase. This power
of attorney and proxy are irrevocable and are granted in consideration of the
acceptance for payment of such shares and Rights in accordance with the terms of
the Offer. Upon such acceptance for payment, all prior powers of attorney,
proxies and consents given by the undersigned with respect to such shares and
Rights (and any such other shares and Rights or securities or rights) will,
without further action, be revoked and no subsequent powers of attorney,
proxies, consents or revocations may be given (and, if given, will not be
effective) by the undersigned.

    The undersigned understands that the valid tender of shares and/or Rights
pursuant to any of the procedures described in Section 2 of the Offer to
Purchase and in the Instructions hereto will constitute a binding agreement
between the undersigned and the Purchaser upon the terms and subject to the
conditions of the Offer.

    Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the purchase price and/or return any certificates for
shares and/or Rights not tendered or accepted for payment in the name(s) of the
registered holder(s) appearing under "Description of Shares and/or Rights

Instructions," please mail the check for the purchase price and/or return any
certificates for shares and/or Rights not tendered or not accepted for payment

registered holder(s) appearing under "Description of Shares and/or Rights
Tendered." In the event that both "Special Delivery Instructions" and "Special
Payment Instructions" are completed, please issue the check for the purchase
price and/or return any certificates for shares or Rights not tendered or not
accepted for payment (and any accompanying documents, as appropriate) in the
name of, and deliver such check and/or return such certificates (and any

obligation pursuant to "Special Payment Instructions" to transfer any shares or
Rights from the name of the registered holder thereof if the Purchaser does not
accept for payment any of the shares so tendered.

                                  INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

    1. GUARANTEE OF SIGNATURES. Your signature on this Letter of Transmittal
must be guaranteed unless (a) this Letter of Transmittal is signed by the
registered holder(s) (which term, for purposes of this Instruction 1, includes
any participant in the Book-Entry Transfer Facility's system whose name appears
on a security position listing as the owner of the shares and/or Rights) of the
shares and/or Rights tendered herewith and such registered holder(s) has not
completed either the box entitled "Special Payment Instructions" or the box
entitled "Special Delivery Instructions" on this Letter of Transmittal or (b) if
such shares and/or Rights are tendered for the account of a financial
institution (including most commercial banks, savings and loan associations and
brokerage houses) that is a participant in the Security Transfer Agents
Medallion Program, the New York Stock Exchange Medallion Signature Guarantee
Program or the Stock Exchange Medallion Program (such participant, an "Eligible
Institution"). If a signature is required, it must be provided by an Eligible
Institution. See Instruction 5.

    2. REQUIREMENTS OF TENDER. This Letter of Transmittal is to be completed by
stockholders either if certificates are to be forwarded herewith or, unless an
Agent's Message (as defined below) is utilized, if delivery of the shares and/or
Rights is to be made pursuant to the procedures for book-entry transfer set
forth in Section 2 of the Offer to Purchase. For a stockholder validly to tender
shares and/or Rights pursuant to the Offer, either (a) a Letter of Transmittal
(or a facsimile thereof), properly completed and duly executed, together with
any required signature guarantees, or, in the case of a book-entry transfer, an
Agent's Message, and any other required documents, must be received by the
Depositary at one of its addresses set forth herein prior to the Expiration Date
and either certificates for tendered shares and, if applicable, Rights must be
received by the Depositary at one of such addresses or shares and/or Rights must
be delivered pursuant to the procedures for book-entry transfer described herein
(and a Book-Entry Confirmation received by the Depositary) or (b) the tendering
stockholder must comply with the guaranteed delivery procedures described below
and in Section 2 of the Offer to Purchase.

    If your shares and/or Rights are not immediately available or you cannot
deliver your certificates and all other required documents to the Depositary or
complete the procedures for book-entry transfer prior to the Expiration Date,
your tender may be effected if all the following conditions are met:

        (i) your tender is made by or through an Eligible Institution;

        (ii) you ensure that a properly completed and duly executed Notice of
    Guaranteed Delivery, substantially in the form provided by us, is received
    by the Depositary, as provided below, prior to the Expiration Date; and

        (iii) you ensure that the certificates for all tendered shares and/or
    Rights, in proper form for transfer (or a Book-Entry Confirmation with
    respect to all such shares and/or Rights), together with a Letter of
    Transmittal (or a facsimile thereof), properly completed and duly executed,
    with any required signature guarantees, or, in the case of a book-entry
    transfer, an Agent's Message, and any other required documents are received
    by the Depositary within three trading days after the date of execution of
    such Notice of Guaranteed Delivery. A "trading day" is any day on which the
    New York Stock Exchange (the "NYSE") is open for business.

    The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation which states that such Book-Entry Transfer Facility has
received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the shares and/or Rights that such participant has
received and agrees to be bound by the terms of the Letter of Transmittal and
that the Purchaser may enforce such agreement against the participant.

    THE METHOD OF DELIVERY OF SHARES AND/OR RIGHTS, THE LETTER OF TRANSMITTAL
AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY
TRANSFER FACILITY, IS AT THE ELECTION AND RISK OF THE TENDERING STOCKHOLDER.
SHARES AND/OR RIGHTS WILL BE DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE
DEPOSITARY (INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY
CONFIRMATION). IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT
REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

    No alternative, conditional or contingent tenders will be accepted and no
fractional shares will be purchased. All tendering stockholders, by execution of
this Letter of Transmittal (or facsimile hereof), waive any right to receive any
notice of the acceptance of their shares and/or Rights for payment.

    3. INADEQUATE SPACE. If the space provided herein is inadequate, the
certificate numbers and/or the number of shares and/or Rights should be listed
on a separate schedule attached hereto.

    4. PARTIAL TENDERS (APPLICABLE TO CERTIFICATED SHARES). If fewer than all
the shares and/or Rights evidenced by any certificate submitted are to be
tendered, fill in the number of shares and/or Rights that are to be tendered in
the boxes entitled "Number of Shares Tendered" and "Number of Rights Tendered."
In any case, new certificate(s) for the remainder of the shares and/or Rights
(if applicable) that were evidenced by the old certificate(s) will be sent to
the registered holder, unless otherwise provided in the appropriate box on this
Letter of Transmittal, as soon as practicable after the acceptance

                                        8
   9

for payment of, and payment for, the shares and/or Rights tendered herewith. All
shares and/or Rights (if applicable) represented by certificates delivered to
the Depositary will be deemed to have been tendered unless otherwise indicated.

    5. SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder of the shares
and/or Rights tendered hereby, the signature must correspond with the name as
written on the face of the certificate(s) without any change whatsoever.

    If any of the shares and/or Rights tendered hereby are owned of record by
two or more joint owners, all such owners must sign this Letter of Transmittal.

    If any tendered shares and/or Rights are registered in different names on
several certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of
certificates.

    If this Letter of Transmittal or any certificates or stock powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and proper evidence satisfactory to the
Purchaser of their authority so to act must be submitted.

    When this Letter of Transmittal is signed by the registered owner(s) of the
shares and/or Rights listed and transmitted hereby, no endorsements of
certificates or separate stock powers are required unless payment is to be made
to, or certificates for shares and/or Rights not tendered or accepted for
payment are to be issued to, a person other than the registered owner(s).
Signatures on such certificates or stock powers must be guaranteed by an
Eligible Institution.

    If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the certificates listed, the certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered owner or owners appear on the
certificates. Signatures on such certificates or stock powers must be guaranteed
by an Eligible Institution.

    6. STOCK TRANSFER TAXES. The Purchaser will pay any stock transfer taxes
with respect to the transfer and sale of shares and/or Rights to it or its order
pursuant to the Offer. If, however, payment of the purchase price is to be made
to, or if certificates for shares and/or Rights not tendered or accepted for
payment are to be registered in the name of, any person(s) other than the
person(s) signing this Letter of Transmittal, the amount of any stock transfer
taxes (whether imposed on the registered owner(s) or such person(s)) payable on
account of the transfer to such person(s) will be deducted from the purchase
price unless satisfactory evidence of the payment of such taxes or exemption
therefrom is submitted.

    EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER OF
TRANSMITTAL.

    7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check is to be issued in
the name of, and/or certificates for shares and/or Rights not accepted for
payment are to be returned to, a person other than the signer of this Letter of
Transmittal or if a check is to be sent and/or such certificates are to be
returned to a person other than the signer of this Letter of Transmittal or to
an address other than that shown above, the appropriate boxes on this Letter of
Transmittal should be completed.

    8. WAIVER OF CONDITIONS. The Purchaser reserves the right, subject to the
terms and conditions contained in the applicable rules and regulations of the
Commission, to waive any of the specified conditions of the Offer, in whole or
in part, in the case of any shares or Rights tendered.

    9. 31% BACKUP WITHHOLDING. In order to avoid backup withholding of Federal
income tax on payments of cash pursuant to the Offer, when surrendering shares
and/or Rights in the Offer, unless an exemption applies, you must provide the
Depositary with your correct taxpayer identification number ("TIN") on
Substitute Form W-9 below in this Letter of Transmittal and certify under
penalties of perjury that such TIN is correct and that you are not subject to
backup withholding. If you do not provide your correct TIN or fail to provide
the certifications described above, the Internal Revenue Service (the "IRS") may
impose a $50.00 penalty on you, and payment of cash to you pursuant to the Offer
may be subject to backup withholding of 31%.

    Backup withholding is not an additional income tax. Rather, the amount of
the backup withholding can be credited against the U.S. federal income tax
liability of the person subject to the backup withholding, provided that the
required information is given to the IRS. If backup withholding results in an
overpayment of tax, a refund can be obtained by the stockholder upon filing an
income tax return.

    You are required to give the Depositary the TIN (i.e., social security
number or employer identification number) of the record owner of the shares and
Rights. If the shares and/or Rights are held in more than one name or are 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.

    The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
stockholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
stockholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% on all payments made prior to the time a properly certified TIN is

                                        9
   10

provided to the Depositary. However, such amounts will be refunded to such
stockholder if a TIN is provided to the Depositary within 60 days.

    Certain stockholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding.
Noncorporate foreign stockholders should complete and sign the main signature
form and a Form W-8, Certificate of Foreign Status, a copy of which may be
obtained from the Depositary, in order to avoid backup withholding. See the
enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for more instructions.

    10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for
assistance or additional copies of the Offer to Purchase, this Letter of
Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 may be
directed to the Information Agent at its address set forth below.

    11. LOST, DESTROYED OR STOLEN CERTIFICATES. If any certificate representing
shares and/or Rights has been lost, destroyed or stolen, the stockholder should
promptly notify the Depositary by checking the box immediately preceding the
special payment/special delivery instructions and indicating the number of
shares and/or Rights lost. The stockholder will then be instructed as to the
steps that must be taken in order to replace the certificate. This Letter of
Transmittal and related documents cannot be processed until the procedures for
replacing lost or destroyed certificates have been followed.

    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE HEREOF), TOGETHER WITH
ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY TRANSFER, AN
AGENT'S MESSAGE, AND ANY OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE
DEPOSITARY PRIOR TO THE EXPIRATION DATE AND EITHER CERTIFICATES FOR TENDERED
SHARES AND/OR RIGHTS MUST BE RECEIVED BY THE DEPOSITARY OR SHARES AND/OR RIGHTS
MUST BE DELIVERED PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH
CASE PRIOR TO THE EXPIRATION DATE, OR THE TENDERING STOCKHOLDER MUST COMPLY WITH
THE PROCEDURES FOR GUARANTEED DELIVERY.
