warrants that it acquired the Old Notes for its own account as a result of
market-making activities or other trading activities and (ii) it hereby
acknowledges that it will deliver a prospectus meeting the requirements of the
Securities Act of 1933, as amended (the "Securities Act"), in connection with
any resale of the Notes received hereby. The acknowledgment contained in the
foregoing sentence shall not be deemed an admission that the undersigned is an

     7. Any obligation of the undersigned hereunder shall be binding upon the
successors, assigns, executors, administrators, trustees in bankruptcy and legal
and personal representatives of the undersigned.

RETURN RECEIPT), PROPERLY INSURED, IS SUGGESTED.
 
     3. GUARANTEED DELIVERY PROCEDURES. Registered 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, the Letter of Transmittal or any other
required documents to the Exchange Agent prior to the Expiration Date, may

          (a) The tender is made through an Eligible Institution;
 
          (b) Prior to the Expiration Date, the Exchange Agent receives from
     such Eligible Institution a properly completed and duly executed Notice of
     Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
     setting forth the name and address of the registered holder of the Old
     Notes, the certificate number or numbers of such Old Note(s) and the

     If this Letter of Transmittal or any Old Notes or bond power is signed by

corporations or others acting in a fiduciary or representative capacity, such
person should so indicate when signing, and, unless waived by the Company,

(including time of receipt), acceptance and withdrawal of tendered Old Notes
will be resolved by the Company, whose determination will be final and binding.
The Company reserves the absolute right to reject any or all tenders that are
not in proper form or the 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
   6
 
this Letter of Transmittal) will be final and binding. Unless waived, any
irregularities in connection with tenders or consents must be cured within such
time as the Company shall determine. Neither the Company nor the Exchange Agent
shall be under any duty to give notification of defects in such tenders or shall
incur liabilities for failure to give such notification. Tenders of Old Notes
will not be deemed to have been made until such irregularities have been cured
or waived. Any Old Notes received by the Exchange Agent that are not properly
tendered and as to which the irregularities have not been cured or waived will
be returned by the Exchange Agent to the tendering holder thereof.
 
                           IMPORTANT TAX INFORMATION
 
     Under current Federal income tax law, an Old Noteholder whose tendered Old
Notes are accepted for payment generally is required to provide the Exchange
Agent (as agent for the payer) with his or her correct taxpayer identification
number ("TIN") on Substitute Form W-9 below. If such Old Noteholder is an
individual, the TIN is his or her social security number. If the Exchange Agent
is not provided with the correct TIN, the Old Noteholder may be subject to a $50
penalty imposed by the Internal Revenue Service. In addition, payments that are
made to such Old Noteholders with respect to New Notes exchanged pursuant to the
Offer may be subject to backup withholding.
 
     Certain Old Noteholders (including, among others, all corporations and
certain foreign individuals) may not be subject to these backup withholding and
reporting requirements. Exempt Old Noteholders should indicate their exempt
status on Substitute Form W-9. In order for a foreign individual to qualify as
an exempt recipient, that Old Noteholder must submit a properly completed
Internal Revenue Service Form W-8, signed under penalties of perjury, attesting
to his or her exempt status. Such statements 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 percent of any such payments made to the Old Noteholder. Backup withholding
is not an additional 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.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
     To prevent backup withholding on payments that are made to an Old
Noteholder with respect to Old Notes exchanged pursuant to the Offer, each Old
Noteholder is required to notify the Exchange Agent of his, her or its correct
TIN by completing the Substitute Form W-9 below certifying the TIN provided on
such form is correct (or that such Old Noteholder is awaiting a TIN) and that
(1) the Old Noteholder has not been notified by the Internal Revenue Service
that he, she or it is subject to backup withholding as a result of a failure to
report all interest or dividends or (2) the Internal Revenue Service has
notified the Old Noteholder that he, she or it is no longer subject to backup
withholding.
   7
 
What NUMBER TO GIVE THE EXCHANGE AGENT
 
     The Old Noteholder is required to give the Exchange Agent the social
security number or employer identification number of the record owner of the Old
Notes. If the Old Notes are 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 guidelines on which
number to report.
