into the Exchange Agent's account at DTC pursuant to the procedure for
book-entry transfer, described in the Prospectus at "The Exchange
Offer -- Book-Entry Transfer," must be received by the Exchange Agent prior to
the Expiration Date or (iii) the holder must comply with the guaranteed delivery
procedures described in the Prospectus at "The Exchange Offer -- Guaranteed
Delivery Procedures."
 
     Holders who wish to tender their Original Notes (i) whose Certificates and
are not immediately available, (ii) who cannot deliver their Certificates and
all other required documents to the Exchange Agent on or prior to the Expiration
Date or (iii) who cannot complete the procedures for book-entry transfer on or

guaranteed delivery procedures set forth in "The Exchange Offer -- Guaranteed
Delivery Procedures" in the Prospectus.
 
     The Notice of Guaranteed Delivery must be delivered by hand, overnight
courier or mail, or transmitted by facsimile transmission, to the Exchange Agent
on or prior to the Expiration Date, and must include a guarantee by an Eligible
Institution in the form set forth in such notice. For Original Notes to be
properly tendered pursuant to the guaranteed delivery procedure, the Exchange
Agent must receive a Notice of Guaranteed Delivery on or prior to the Expiration
Date. As used herein and in the Prospectus, "Eligible Institution" means a firm
or other entity identified in Rule 17Ad-15 under the Exchange Act as an
"eligible guarantor institution."
 
     THE METHOD OF DELIVERY OF CERTIFICATES, THIS LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER
AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE
AGENT. AN OVERNIGHT DELIVERY SERVICE IS RECOMMENDED OR, 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 ON OR
PRIOR TO THE EXPIRATION DATE.
 
     The Company will not accept any alternative, conditional or contingent
tenders. Each tendering holder, by book-entry transfer or execution of a Letter
of Transmittal (or facsimile thereof), waives any right to receive any notice of
the acceptance of such tender.
 
     2.  GUARANTEE OF SIGNATURES.  No signature guarantee on this Letter of
Transmittal is required if:
 
     (i) this Letter of Transmittal is signed by the registered holder (which
         term, for purposes of this document, shall include any participant in
         DTC whose name appears on a security position listing as the owner of
         the Original Notes) of Original Notes tendered herewith, unless such
         holder has completed either the box entitled "Special Issuance
         Instructions" or the box entitled "Special Delivery Instructions"
         above; or
 
     (ii) such Original Notes are tendered for the account of a firm that is an
          Eligible Institution. In all other cases, an Eligible Institution must
          guarantee the signature on this Letter of Transmittal. See Instruction
          5.
 
     3.  INADEQUATE SPACE.  If the space provided in the box captioned
"Description of Original Notes Tendered" is inadequate, the Certificate numbers
and/or principal amount of Original Notes and any other
   10
 
required information should be listed on a separate signed schedule which is
attached to this Letter of Transmittal.
 
     4.  PARTIAL TENDERS AND WITHDRAWAL RIGHTS.  Tenders of Original Notes will
be accepted only in denominations of $1,000 principal amount and integral
multiples thereof. If less than all the Original Notes evidenced by any
Certificate submitted are to be tendered, fill in the Principal Amount of
Original Notes which are to be tendered in the box entitled "Principal Amount of
Original Notes Tendered (If Less than All are Tendered)." In such case, a new
Certificate for the remainder of the Original Notes that were evidenced by your
old Certificate will be sent to the holder of the Original Notes, promptly after
the Expiration Date unless the appropriate boxes on this Letter of Transmittal
are completed. All Original Notes represented by Certificates delivered to the
Exchange Agent will be deemed to have been tendered unless otherwise indicated.
 
     Except as otherwise provided herein, tenders of Original Notes may be
withdrawn at any time on or prior to the Expiration Date, unless previously
accepted for exchange. See "The Exchange Offer -- Withdrawal Rights."
 
     To withdraw a tender of Original 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 the Expiration Date and prior to
acceptance for exchange thereof by the Company. Any such notice of withdrawal
must (i) specify the name of the person having deposited the Original Notes to
be withdrawn (the "Depositor"), (ii) identify the Original Notes to be withdrawn
(including, if applicable, the registration number or numbers and total
principal amount of such Original Notes), (iii) be signed by the Depositor in
the same manner as the original signature on the Letter of Transmittal by which
such Original Notes were tendered (including any required signature guarantees)
or be accompanied by documents of transfer sufficient to permit the Trustee with
respect to the Original Notes to register the transfer of such Original Notes
into the name of the Depositor withdrawing the tender, (iv) specify the name in
which any such Original Notes are to be registered, if different from that of
the Depositor and (v) if applicable because the Original Notes have been
tendered pursuant to the book-entry procedures, specify the name and number of
the participant's account at DTC to be credited, if different than that of the
Depositor.
 
     All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, whose
determination shall be final and binding on all parties. Any Original 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 Original Notes so withdrawn are validly retendered. Any Original Notes which
have been tendered but which are not accepted for exchange will be returned to
the holder thereof without cost to such holder as soon as practicable after
withdrawal, rejection or termination of the Exchange Offer. Properly withdrawn
Original Notes may be retendered by following one of the procedures described in
the Prospectus, "The Exchange Offer -- Procedures for Tendering," at any time
prior to the Expiration Date.
 
     Neither the Company, any affiliates or assigns of the Company, the Exchange
Agent nor any other person shall not be under any duty to give any notification
of any irregularities in any notice of withdrawal or incur any liability for
failure to give any such notification. Any Original Notes which have been
tendered but which are withdrawn on or prior to the Expiration Date will be
returned to the holder thereof without cost to such holder promptly after
withdrawal.
 
     5.  SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS.  If
this Letter of Transmittal is signed by the record holder(s) of the Original
Notes tendered thereby, the signature must correspond with the name(s) written
on the face of the Original Notes without alteration, enlargement or any change
whatsoever.
 
     If this Letter of Transmittal is signed by a participant in DTC, the
signature must correspond with the name as it appears on the security position
listing as the holder of the Original Notes.
 
     If this Letter of Transmittal is signed by a person other than the
registered holder of the Original Notes listed therein, such Original Notes must
be endorsed or accompanied by appropriate bond powers which authorize such
person to tender the Original Notes on behalf of the registered holder, in
either case signed as the name of the registered holder or holders appears on
the Original Notes.
   11
 
     If this Letter of Transmittal or any Original Notes or bond 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 unless waived by the
Company, evidence satisfactory to the Company of their authority to so act must
be submitted with this Letter of Transmittal.
 
     Signatures on this Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution unless the Original
Notes tendered pursuant thereto are tendered (i) by a registered holder who has
not completed the box entitled "Special Issuance Instructions" or "Special
Delivery Instructions" on this Letter of Transmittal or (ii) for the account of
an Eligible Institution. In the even that signatures on a Letter of Transmittal
or a notice of withdrawal, as the case may be, are required to be guaranteed,
such guarantee must be by a member firm of a registered national securities
exchange or of the National Association of Securities Dealers, Inc., a
commercial bank or trust company having an office or correspondent in the United
States or another "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act.
 
     6.  SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  If Exchange Notes are to
be issued in the name of a person other than the registered holder, or if
Exchange Notes are to be sent to someone other than the registered holder or to
an address other than that shown above, the appropriate boxes on this Letter of
Transmittal should be completed. Certificates for Original Notes not exchanged
will be returned by mail or, if tendered by book-entry transfer, by crediting
the account indicated above maintained at DTC unless the appropriate boxes on
this Letter of Transmittal are completed. See Instruction 5.
 
     7.  IRREGULARITIES.  All questions as to the validity, form, eligibility
(including time of receipt), acceptance and withdrawal of the tendered Original
Notes will be determined by the Company in its sole discretion, which
determination will be final and binding. The Company reserves the absolute right
to reject any and all Original Notes not properly tendered or any Original Notes
the Company's acceptance of which would, in the opinion of the Company or its
counsel, be unlawful. The Company also reserves the absolute right to waive any
of the conditions of the Exchange Offer or any defect or irregularity in tender
of any Original 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 Original 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 Original Notes or incur any
liability for failure to give such notification. Tenders of Original Notes will
not be deemed to have been made until such defects or irregularities have been
cured or waived. Any Original 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,
unless otherwise provided in this Letter of Transmittal, as soon as practicable
following the Expiration Date. See the Prospectus, "The Exchange
Offer -- Procedures for Tendering."
 
     8.  QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES.  Questions
and requests for assistance may be directed to the Exchange Agent at its address
and telephone number set forth on the front of this Letter of Transmittal.
Additional copies of the Prospectus, the Notice of Guaranteed Delivery and this
Letter of Transmittal may be obtained from the Exchange Agent or from your
broker, dealer, commercial bank, trust company or other nominee.
 
     9.  31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9.  Under U.S. Federal income
tax law, a holder whose tendered Original Notes are accepted for exchange is
required to provide the Exchange Agent with such holder's correct taxpayer
identification number ("TIN") on the Substitute Form W-9 below. If the Exchange
Agent is not provided with the correct TIN, the Internal Revenue Service (the
"IRS") may subject the holder or other payee to a $50 penalty. In addition,
payments to such holders or other payees with respect to Original Notes
exchanged pursuant to the Exchange Offer may be subject to 31% backup
withholding.
 
     The box in Part 3 of the Substitute Form W-9 may be checked if the
tendering holder 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
holder 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 Exchange Agent will
withhold 31% of all payments
   12
 
made prior to the time a properly certified TIN is provided to the Exchange
Agent. The Exchange Agent will retain such amounts withheld during the 60 day
period following the date of the Substitute Form W-9. If the holder furnishes
the Exchange Agent with its TIN within 60 days after the date of the Substitute
Form W-9, the amounts retained during the 60 day period will be remitted 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 with its TIN within such 60 day period, amounts withheld will be remitted
to the IRS as backup withholding. In addition, 31% of all payments made
thereafter will be withheld and remitted to the IRS until a correct TIN is
provided.
 
     The holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered owner of
the Original Notes or of the last transferee appearing on the transfers attached
to, or endorsed on, the Original Notes. If the Original Notes are registered 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.
 
     Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below, and write "exempt" on the face
thereof, to avoid possible erroneous backup withholding. A foreign person may
qualify as an exempt recipient by submitting a properly completed IRS Form W-8,
signed under penalties of perjury, attesting to that holder's exempt status.
Please consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
holders are exempt from backup withholding.
 
     Backup withholding is not an additional U.S. Federal income tax. Rather,
the U.S. 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.
 
     10.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any Certificates
representing Original Notes have been lost, destroyed or stolen, the holder
should promptly notify the Exchange Agent. The holder will then be instructed as
to the steps that must be taken in order to replace the Certificates. This
Letter of Transmittal and related documents cannot be processed until the
procedures for replacing lost, destroyed or stolen Certificates have been
followed.
 
     11.  SECURITY TRANSFER TAXES.  Holders who tender their Original Notes for
exchange will not be obligated to pay any transfer taxes in connection
therewith. If, however, Exchange Notes are to be delivered to, or are to be
issued in the name of, any person other than the registered holder of the
Original Notes tendered, or if a transfer tax is imposed for any reason other
than the exchange of Original Notes in connection with the Exchange Offer, then
the amount of any such transfer tax (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 with
the Letter of Transmittal, the amount of such transfer taxes will be billed
directly to such tendering holder.
 
     IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF OR AGENT'S
       MESSAGE IN LIEU THEREOF) AND ALL OTHER REQUIRED DOCUMENTS MUST BE
       RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO THE EXPIRATION DATE.
