    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 New
Notes. If the undersigned is a broker-dealer that will receive New Notes for its
own account in exchange for Existing 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 New 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.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY
 
Ladies and Gentlemen:
 
    Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount of
Existing Notes indicated above. Subject to, and effective upon, the acceptance
for exchange of the Existing Notes tendered hereby, the undersigned hereby
sells, assigns and transfers to, or upon the order of, the Company all right,
title and interest in and to such Existing Notes as are being tendered hereby.
 
    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Existing Notes
tendered hereby and that 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 when the same are accepted by the Company. The
undersigned will, upon request, execute and deliver any additional documents
deemed by the Company or the Exchange Agent to be necessary or desirable to
complete the sale, assignment and transfer of the Existing Notes tendered
hereby.
 
    The undersigned also acknowledges that this Exchange Offer is being made in
reliance on the Company's belief, based on interpretations by the staff of the
Securities and Exchange Commission (the "SEC") to third parties in unrelated
transactions, that the New Notes issued in exchange for the Existing Notes
pursuant to the Exchange Offer may be offered for resale, resold and otherwise
transferred by holders thereof (other than (i) any such holder that is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act of 1933, as amended (the "Securities Act") or (ii) any broker-dealer that
purchase Notes from the Company to resell pursuant to Rule 144A under the
Securities Act "Rule 144A") or any other available exemption) without compliance
with the registration and prospectus delivery provisions of the Securities Act
provided that such New 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 New Notes. The undersigned acknowledges
that any holder of Existing Notes using the Exchange Offer to participate in a
distribution of the New Notes (i) cannot rely on the position of the staff of
the SEC enunciated in its interpretive letter with respect to Exxon Capital
Holdings Corporation (available April 13, 1989) or similar letters and (ii) must
comply with the registration and prospectus requirements of the Securities Act
in connection with a secondary resale transaction.
 
    The undersigned represents that (i) the New Notes acquired pursuant to the
Exchange Offer are being obtained in the ordinary course of such holder's
business, (ii) such holder has no arrangements with any person to participate in
the distribution of such New Notes, and (iii) such holder is not an "affiliate,"
as defined in Rule 405 under the Securities Act, of the Company or, if such
holder is an affiliate, that such holder will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable.
 
    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 New
Notes. If the undersigned is a broker-dealer that will receive New Notes for its
own account in exchange for Existing Notes that were acquired as a result of
market-making activities or other trading 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 New 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.
 
    The undersigned, if a California resident, hereby further represents and
warrants that the undersigned (or the beneficial owner of the Existing Notes
tendered hereby, if not the undersigned) (i) is a bank, savings and loan
association, trust company, insurance company, investment company registered
under the Investment Company Act of 1940, pension or profit-sharing trust (other
than a pension or profit-sharing trust of the Company, a self-employed
individual retirement plan, or individual retirement account), or a corporation
which has a net worth on a consolidated basis according to its most recent
audited financial statement of not less than $14,000,000, and (ii) is
acquiring the New Notes for its own account for investment purposes (or for the
account of the beneficial owner of such New Notes for investment purposes).
 
    All authority conferred or agreed to be conferred in this Letter and every
obligation of the undersigned hereunder shall be binding upon the successors,
assigns, heirs, executors, administrators, trustees in bankruptcy and legal
representatives of the undersigned and shall not be affected by, and shall
survive, the death or incapacity of the undersigned. This tender may be
withdrawn only in accordance with the procedures set forth in the instructions
contained in this Letter.

    The undersigned understands that tenders of the Existing Notes pursuant to
any one of the procedures described under "The Exchange Offer--Procedures for
Tendering Existing Notes" in the Prospectus and in the instructions hereto will
constitute a binding agreement between the undersigned and the Company in
accordance with the terms and subject to the conditions of the Exchange Offer.
 
    The undersigned recognizes that, under certain circumstances set forth in
the Prospectus under "The Exchange Offer--Certain Conditions to the Exchange
Offer," the Company may not be required to accept for exchange any of the
Existing Notes tendered. Existing Notes not accepted for exchange or withdrawn
will be returned to the undersigned at the address set forth below unless
otherwise indicated under "Special Delivery Instructions" below.
 
    Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, please issue the New Notes (and, if applicable, substitute
certificates representing Existing Notes for any Existing Notes not exchanged)
in the name of the undersigned. Similarly, unless otherwise indicated under the
box entitled "Special Delivery Instructions" below, please deliver the New Notes
(and, if applicable, substitute certificates representing Existing Notes for any
Existing Notes not exchanged) to the undersigned at the address shown above in
the box entitled "Description of Existing Notes."

                                  INSTRUCTIONS
         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
 
1. DELIVERY OF THIS LETTER AND EXISTING NOTES; GUARANTEED DELIVERY PROCEDURE.
 
    This Letter is to be used to forward, and must accompany, all certificates
representing Existing Notes tendered pursuant to the Exchange Offer.
Certificates representing the Existing Notes in proper form for transfer (or a
confirmation of book-entry transfer of such Existing Notes into the Exchange
Agent's account at the book-entry transfer facility) must be received by the
Exchange Agent at its address set forth herein on or before the Expiration Date.
 
    THE METHOD OF DELIVERY OF THIS LETTER, THE EXISTING NOTES AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE TENDERING HOLDERS, BUT THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED OR CONFIRMED BY THE
EXCHANGE AGENT. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED
MAIL PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO PERMIT TIMELY DELIVERY.
 
    If a holder desires to tender Existing Notes and such holder's Existing
Notes are not immediately available or time will not permit such holder's Letter
of Transmittal, Existing Notes (or a confirmation of book-entry transfer of
Existing Notes into the Exchange Agent's account at the book-entry transfer
facility) or other required documents to reach the Exchange Agent on or before
the Expiration Date, such holder's tender may be effected if:
 
        (a) such tender is made by or through an Eligible Institution (as
    defined below);
 
        (b) on or prior to the Expiration Date, the Exchange Agent has received
    a telegram, facsimile transmission (receipt confirmed by telephone and an
    original delivered by guaranteed overnight courier) or letter from such
    Eligible Institution setting forth the name and address of the holder of
    such Existing Notes tendered and stating that the tender is being made
    thereby and guaranteeing that, within three business days after the
    Expiration Date, a duly executed Letter of Transmittal, or facsimile
    thereof, together with the Existing Notes (or a confirmation of book-entry
    transfer of such Existing Notes into the Exchange Agent's account at the
    book-entry transfer facility), and any other documents required by this
    Letter and the instructions hereto, will be deposited by such Eligible
    Institution with the Exchange Agent; and
 
        (c) this Letter, or a facsimile hereof, and Existing Notes in proper
    form for transfer (or a confirmation of book-entry transfer of such Existing
    Notes into the Exchange Agent's account at the book-entry transfer facility)
    and all other required documents are received by the Exchange Agent within
    three business days after the Expiration Date.
 
    See "The Exchange Offer--Procedures for Tendering Existing Notes" in the
Prospectus.
 
2. WITHDRAWALS.
 
    Any holder who has tendered Existing Notes may withdraw the tender by
delivering written notice of withdrawal (which may be sent by telegram,
facsimile (receipt confirmed by telephone and an original delivered by
guaranteed overnight courier)) to the Exchange Agent prior to the Expiration
Date. For a withdrawal to be effective, a written notice of withdrawal must be
received by the Exchange Agent at its address set forth herein. Any such notice
of withdrawal must (i) specify the name of the person having tendered the
Existing Notes to be withdrawn (the "Depositor"), (ii) identify the Existing
Notes to be withdrawn (including the certificate number or numbers and principal
amount of such Existing Notes), (iii) be timely received and signed by the
holder in the same manner as the original signature on the Letter by which such
Existing Notes were tendered or as otherwise set forth in Instruction 3 below
(including any required signature guarantees), or be accompanied by documents of
transfer sufficient to have the Trustee (as defined in the Prospectus) register
the transfer of such Existing Notes pursuant to the terms of the Indenture into
the name of the person withdrawing the tender and (iv) specify the name in which
any such Existing Notes are to be registered, if different from that of the
Depositor. If Existing Notes have been tendered pursuant to the procedure for
book-entry transfer, any notice of withdrawal must specify the name and number
of the account at the book-entry transfer facility to be credited with the
withdrawn Existing Notes or otherwise comply with the book-entry transfer
facility's procedures. See "The Exchange Offer--Withdrawal Rights" in the
Prospectus.

3. SIGNATURES ON THIS LETTER; BOND POWERS AND ENDORSEMENTS; GUARANTEE OF
  SIGNATURES.
 
    If this Letter is signed by the registered holder of the Existing Notes
tendered hereby, the signature must correspond exactly with the name as written
on the face of the certificates without any change whatsoever.
 
    If any tendered Existing Notes are owned of record by two or more joint
owners, all such owners must sign this Letter.
 
    If any tendered Existing Notes are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
copies of this Letter as there are different registrations of certificates.
 
    The signatures on this Letter or a notice of withdrawal, as the case may be,
must be guaranteed unless the Existing Notes surrendered for exchange pursuant
thereto are tendered (i) by a registered holder of the Existing Notes who has
not completed the box entitled "Special Issuance Instructions" or "Special
Delivery Instructions" in this Letter or (ii) for the account of an Eligible
Institution. In the event that the signatures in this Letter or a notice of
withdrawal, as the case may be, are required to be guaranteed, such guarantees
must be by a firm which is a member of a registered national securities exchange
or a member of the National Association of Securities Dealers, Inc., a clearing
agency, an insured credit union, a savings association or by a commercial bank
or trust company having an office or correspondent in the United States
(collectively, "Eligible Institutions"). If Existing Notes are registered in the
name of a person other than the signer of this Letter, the Existing Notes
surrendered for exchange must be endorsed by, or be accompanied by a written
instrument or instruments of transfer or exchange, in satisfactory form as
determined by the Company in its sole discretion, duly executed by the
registered holder with the signature thereon guaranteed by an Eligible
Institution.
 
4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.
 
    Tendering holders of Existing Notes should indicate in the applicable box
the name and address to which New Notes issued pursuant to the Exchange Offer
are to be issued or sent, if different from the name or address of the person
signing this Letter. In the case of issuance in a different name, the employer
identification or social security number of the person named must also be
indicated. If no such instructions are given, any New Notes will be issued in
the name of, and delivered to, the name or address of the person signing this
Letter and any Existing Notes not accepted for exchange will be returned to the
name or address of the person signing this Letter.

5. 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 New 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 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 I, the Company (or
the Paying Agent under the Indenture governing the New Notes) shall retain 31%
of payments made to the tendering holder during the sixty (60) day period
following the date of the Substitute Form W-9. If the holder furnishes the
Exchange Agent or the Company with his or her TIN within sixty (60) days after
the date of the Substitute Form W-9, the Company (or the Paying Agent) shall
remit such amounts retained during the sixty (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 his or her TIN within such sixty (60) day period, the
Company (or the Paying Agent) shall remit such previously retained amounts to
the IRS as backup withholding. In general, if a holder is an individual, the
taxpayer identification number is the Social Security number of such individual.
If the Exchange Agent or the Company is not provided with the correct taxpayer
identification number, the holder may be subject to a $50 penalty imposed by the
IRS. 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, 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 taxpayer identification number if you do not
have one and how to complete the Substitute Form W-9 if Existing 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
Existing 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 New 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.
 
6. TRANSFER TAXES.
 
    The Company will pay all transfer taxes, if any, applicable to the transfer
of Existing Notes to it or its order pursuant to the Exchange Offer. If,
however, New Notes and/or substitute Existing Notes not exchanged are to be
delivered to, or are to be registered or issued in the name of, any person other
than the registered holder of the Existing Notes tendered hereby, or if tendered
Existing Notes are registered in the name of any person other than the person
signing this Letter, or if a transfer tax is imposed for any reason other than
the transfer of Existing Notes to the Company or its order pursuant to the
Exchange Offer, the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted herewith, the amount of such transfer taxes will be billed directly to
such tendering holder.
 
    Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Existing Notes specified in this
Letter.
 
7. WAIVER OF CONDITIONS.
 
    The Company reserves the absolute right to waive satisfaction of any or all
conditions enumerated in the Prospectus.

8. NO CONDITIONAL TENDERS.
 
    No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Existing Notes, by execution of this Letter,
shall waive any right to receive notice of the acceptance of their Existing
Notes for exchange.
 
    Neither the Company nor any other person is obligated to give notice of
defects or irregularities in any tender, nor shall any of them incur any
liability for failure to give any such notice.
 
9. INADEQUATE SPACE.
 
    If the space provided herein is inadequate, the aggregate principal amount
of Existing Notes being tendered and the certificate number or numbers (if
available) should be listed on a separate schedule attached hereto and
separately signed by all parties required to sign this Letter.
 
10. MUTILATED, LOST, STOLEN OR DESTROYED EXISTING NOTES.
 
    If any certificate has been lost, mutilated, destroyed or stolen, the holder
should promptly notify Bankers Trust Company of New York, as Trustee, B.T.
Services Tennessee, Inc. Corporate Trust & Agency Group, Securities Replacement
Unit, 648 Grassmere Park Road, Nashville, TN 37211, Telephone (800) 735-7777.
The holder will then be instructed as to the steps that must be taken to replace
the certificate(s). This Letter of Transmittal and related documents cannot be
processed until the Existing Notes have been replaced.
 
11. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.
 
    Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter, may be directed to the
Exchange Agent at the address and telephone number indicated above.
