By tendering, each Holder of Initial Notes that is a broker-dealer (whether or not it is also an "affiliate") that will receive Exchange Notes for its own account pursuant to the Exchange Offer, represents that the Initial Notes to be exchanged for the Exchange Notes were acquired by it as a result of market-making activities or other trading activities, and acknowledges that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such Exchange Notes; however, by so acknowledging and by delivering a prospectus, the Holder will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. The undersigned understands that tenders of Initial Notes pursuant to the procedures described under the captions "The Exchange Offer--Procedures for Tendering" 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, subject only to withdrawal of such tenders on the terms set forth in the Prospectus under the caption "The Exchange Offer--Withdrawal of Tenders." All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned and any Beneficial Owner(s), and every obligation of the undersigned or any Beneficial Owners hereunder shall be binding upon the heirs, representatives, successors, and assigns of the undersigned and such Beneficial Owner(s).

Unless waived, any defects or irregularities in connection with tenders of Initial Notes must be cured within such time as the Company shall determine.

If such Holder is an individual, the TIN is such Holder's social security number. If the Exchange Agent is not provided with the correct taxpayer identification number, the Holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, delivery to such Holder of the Exchange Notes may be subject to backup withholding. Certain Holders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. Exempt Holders should indicate their exempt status on Substitute Form W-9. A foreign individual may qualify as an exempt recipient by submitting to the Exchange Agent a properly completed Internal Revenue Service Form W-8 (which the Exchange Agent will provide upon request) signed under penalty of perjury, attesting to the Holder's exempt status. See the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional instructions. If backup withholding applies, the Company is required to withhold 31% of any payment 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 Internal Revenue Service. WHAT NUMBER TO GIVE THE EXCHANGE AGENT The Holder is required to give the Exchange Agent the social security number or employer identification number of the record owner of the Initial Notes. If the Initial 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 guidance on which number to report. 11 12 - --------------------------------------------------------------------------------------------- PAYER'S NAME: THE FIRST NATIONAL BANK OF CHICAGO - --------------------------------------------------------------------------------------------- Part 1 -- PLEASE PROVIDE YOUR TIN IN THE BOX SUBSTITUTE AT RIGHT AND CERTIFY BY SIGNING AND DATING FORM W-9 BELOW ----------------------------------------------------- - ----------------------------------------------------------------------------------------- TIN Social Security Number or Employer Identification Number ----------------------------------------------------- DEPARTMENT OF THE TREASURY INTERNAL REVENUE SERVICE Name (Please Print) PAYOR'S REQUEST FOR TAXPAYER -------------------------------------------------------- IDENTIFICATION NUMBER (TIN) Address AND CERTIFICATION -------------------------------------------------------- City State Zip Code - -------------------------------------------------------------------------------------------------------- Part 2 -- Awaiting TIN [ ] Please see below. - -------------------------------------------------------------------------------------------------------- Part 3 -- CERTIFICATION-UNDER PENALTIES OF PERJURY, I CERTIFY THAT: (1) the number shown on this form is my correct taxpayer identification number (or a TIN has not been issued to me but I have mailed or delivered an application to receive a TIN or intend to do so in the near future), (2) I am not subject to backup withholding either because I have not been notified by the Internal Revenue Service (the "IRS") that I am subject to backup withholding as a result of a failure to report all interest or dividends or the IRS has notified me that I am no longer subject to backup withholding, and (3) all other information provided on this form is true, correct and complete.

(2) FAILURE TO REPORT CERTAIN PAYMENTS. -- If you fail to include properly on your tax return certain items reported to the IRS such failure will be treated as being due to negligence and will be subject to a penalty of 5% on any portion of an under payment of tax attributable to that failure unless there is clear and convincing evidence to the contrary. (3) 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.
