Any such notice of withdrawal must (i) specify the name of the person having deposited the Original Notes to be withdrawn (the "Depositor"), (ii) identify the Original Notes to be withdrawn (including, if applicable, the registration number or numbers and total principal amount of such Original Notes), (iii) be signed by the Depositor in the same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.

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.
