IRREGULARITIES. The Company will determine, in its sole discretion, all questions as to the form of documents, validity, eligibility (including time of receipt), acceptance and withdrawal of tendered Outstanding Notes, which determination shall be final and binding on all parties. The Company reserves the absolute right to reject any and all tenders determined by it not to be in proper form or the acceptance of which, or exchange for, may, in the view of counsel to the Company, be unlawful. The Company also reserves the absolute right, subject to applicable law, to waive any of the conditions of the Exchange Offer set forth in the Prospectus under "The Exchange Offer -- Conditions" or defects, irregularities or conditions of tender as to particular Outstanding Notes, whether or not similar conditions or irregularities are waived in the case of other holders. The Company's interpretation of the terms and conditions of the Exchange Offer (including this Letter of Transmittal and the instructions hereto) will be final and binding on all parties. No tender of Outstanding Notes will be deemed to have been validly made until all irregularities with respect to such tender have been waived or cured within such time as the Company shall determine. Although the Company intends to notify Holders of defects or irregularities with respect to tenders of Outstanding Notes, neither the Company, any affiliate or assign of the Company or the Exchange Agent nor any person shall be under any duty to give notification of any irregularities in tenders or incur any liability for failure to give such notification. Any Outstanding 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 as soon as practicable following the Expiration Date. 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 the 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 the U.S. Federal income tax law, a Holder whose tendered Outstanding Notes are accepted for exchange is required to provide the Exchange Agent with such Holder's 13 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 the payee to a $50 penalty. In addition, payments to such Holders or other payees with respect to Exchange Notes exchanged pursuant to the Exchange Offer may be subject to 31% backup withholding. The box in Part 3 of 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 certifications in Part 2 and 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 made to the payee 7 days following receipt by the Exchange Agent of the Certificate of Awaiting Taxpayer Identification Number and prior to the time a properly certified TIN is provided to the Exchange Agent. 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 Outstanding Notes or of the last transferee appearing on the transfers attached to, or endorsed on, the Outstanding Notes. If the Outstanding 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 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 applied for. 10. LOST, DESTROYED OR STOLEN CERTIFICATES. If any Certificate(s) representing Outstanding Notes have been lost, destroyed or stolen, the holder should promptly notify the Exchange Agent. The holder will then be instructed by the Exchange Agent as to the steps that must be taken in order to replace the Certificate(s).
