Important Tax Information. Payments made to Holders may be subject to information reporting and backup withholding of U.S. federal income tax, currently at a rate of 24%. To avoid backup withholding, a Holder that is a U.S. person for U.S. federal income tax purposes that does not otherwise establish an exemption should complete and return an Internal Revenue Service (“IRS”) Form W-9, certifying that the Holder is a U.S. person, that the taxpayer identification number (TIN) provided is correct, and that such Holder is not subject to backup withholding. A Holder that is not a U.S. person may qualify as exempt from backup withholding by providing an applicable IRS Form W-8, attesting to the Holder’s foreign status. Such forms may be obtained at the IRS website at www.irs.gov. Failure to provide the correct information may subject the Holder to penalties imposed by the IRS.

(*) No representation is made as to the accuracy of the CUSIP or ISIN numbers either as printed on the Notes or as set forth in this Notice of Redemption, and reliance may be placed only on the other identification numbers printed on the Notes. The redemption of the Notes shall not be affected by any defect in or omission of such numbers.
