      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 the Company the principal amount of Old Notes indicated in Box
I 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 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 and


                                       5
   6


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 Subsidiary 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 -- Expiration Date; Extensions;
Termination; Amendments," 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 written notice of acceptance to the Exchange Agent, at
which time the undersigned's right to withdraw 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 -- Procedure for
Tendering Old Notes" 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.


                                       6

    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 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 -- Procedures for Tendering Old Notes -- Guaranteed Delivery." See
Instruction 1 regarding the completion of this Letter of Transmittal.

                                  INSTRUCTIONS

         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 (i) 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 (ii) 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., E.D.T., 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, 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 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, this 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 this 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


                                       9
   10


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 this Letter of Transmittal and agrees to be bound by
the terms of this 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 "The Exchange Offer -- Procedures
for Tendering Old Notes -- Guaranteed Delivery." 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 -- Procedures
for Tendering Old Notes -- Guaranteed Delivery." 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., E.D.T., 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 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 Box I above. The entire principal amount of Old
Notes delivered to the Exchange Agent will be deemed to have been tendered
unless


                                       10
   11


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., E.D.T., 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., E.D.T., 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 this 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 caption "The Exchange Offer -- Procedures
for Tendering Old Notes" at any time prior to the Expiration Date.

    6. Signatures on this 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 must correspond with
the name(s) as written on the face of such 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


                                       11
   12


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 (the "Substitute Form W-9") and either (i) provide
the correct taxpayer identification number ("TIN") and certify, under penalties
of perjury, that the TIN provided is correct and that (a) 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 (b) the IRS has notified the Holder that the Holder is no longer
subject to backup withholding; or (ii) 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 I of the
Substitute Form W-9, the Company (or the applicable Paying Agent under the
respective Indentures governing such Exchange Notes) shall retain 31% of
payments made to the tendering Holder during the sixty-day period following the
date of the Substitute Form W-9. If the Holder furnishes the Exchange Agent or
the Company with its TIN within 60 days after the date of the Substitute Form
W-9, the Company (or the applicable Paying Agent) shall remit such amounts
retained during the 60-day period to the Holder and no further amounts shall be
retained or withheld from payments made to the Holder thereafter. If, however,
the Holder has not provided the Exchange Agent or the Company with its TIN
within such 60-day period, the Company (or the applicable Paying Agent) shall
remit such previously retained amounts to the IRS as backup withholding. 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 IRS. If
you make a false statement with no reasonable basis that results in no backup
withholding, you are subject to a $500 penalty. Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment. Certain Holders (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. In order for a foreign individual to
qualify as an exempt recipient, such Holder must submit a statement (generally,
the appropriate IRS Form W-8), signed under penalties of perjury, attesting to
that individual'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
TIN 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
applicable 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, a refund may be obtained 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 information under the caption "The Exchange Offer -- Transfer
Taxes" in the Prospectus.

    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 their 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

    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 payment is required to provide the Exchange Agent (as payer) with
such Holder's correct TIN on the Substitute Form W-9 below or otherwise
establish a basis for exemption from backup withholding. If such Holder is an
individual, the TIN is his Social Security Number. If the Exchange Agent is not
provided with the correct TIN, a $50 penalty may be imposed by the IRS, and
payments made pursuant to the Exchange Offer may be subject to backup
withholding. If you make a false statement with no reasonable basis that results
in no backup withholding, you are subject to a $500 penalty. Willfully
falsifying certifications or affirmations may subject you to criminal penalties
including fines and/or imprisonment.

    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 the
Substitute Form W-9. A foreign person may qualify as an exempt recipient by
submitting to the Exchange Agent a properly completed appropriate IRS Form W-8,
signed under penalties of perjury, attesting to that Holder's exempt status. The
appropriate IRS 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 Exchange 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
obtained from the IRS.

PURPOSE OF SUBSTITUTE FORM W-9

    To prevent backup withholding on payments made with respect 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 the Substitute Form W-9 is correct (or that such Holder is awaiting
a TIN) and that (a) the Holder has been notified by the IRS that the Holder is
subject to backup withholding as a result of failure to report all interest or
dividends or (b) the IRS 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 EXCHANGE AGENT

    The Holder is required to give the Exchange 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.

         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 to the payer, 31% of all payments made
to me on account of the Exchange Notes shall be retained until I provide a
Taxpayer Identification Number to the payer and that, if I do not provide my
Taxpayer Identification Number within sixty days, such retained amounts shall be
remitted to the Internal Revenue Service as backup withholding and 31% of all
reportable payments made to me thereafter will be withheld and remitted to the
Internal Revenue Service until I provide a Taxpayer Identification Number.

PRIVACY ACT NOTICE. -- Section 6109 requires most recipients of dividend,

purposes and to help verify the accuracy of your return. Payers must be given
the numbers whether or not recipients are required to file tax returns. Payers
must generally withhold 31% of taxable interest, dividend, and certain other
payments to a payee who does not furnish a taxpayer identification number to a
payer. Certain penalties may also apply.

PENALTIES

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. -- If you
fail to furnish your taxpayer identification number to a payer, you are subject
to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.

(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING. -- If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.

(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION. --Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
