The Power of Attorney granted in this paragraph shall be deemed irrevocable from and after the Expiration Date and coupled with an interest. The undersigned represents and warrants that it has full power and authority to tender, sell, exchange, assign and transfer the Outstanding Notes and to acquire Exchange Notes issuable upon the exchange of such tendered Outstanding Notes, and that when the same are accepted for exchange, the Company will acquire good and unencumbered title to the tendered Outstanding Notes, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim.

GUARANTEED DELIVERY PROCEDURES. Holders who wish to tender their Outstanding Notes and (i) whose Outstanding Notes are not immediately available, (ii) who cannot deliver their Outstanding Notes, the Letter of Transmittal or any other required documents to the Exchange Agent or (iii) who cannot complete the procedures for book-entry transfer, prior to the Expiration Date, may effect a tender if: (a) the tender is made through 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 otherwise an "eligible guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange Act (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 Holder, the certificate number(s) of such Outstanding Notes and the principal amount of Outstanding Notes tendered, stating that the tender is being made thereby and guaranteeing that, within five Nasdaq Stock Market trading days after the Expiration Date, the Letter of Transmittal (or facsimile thereof), together with the certificates representing the Outstanding Notes (or a confirmation of book-entry transfer of such Outstanding Notes into the Exchange Agent's account at the Book-Entry Transfer Facility) and any other documents required by the Letter of Transmittal, will be deposited by the Eligible Institution with the Exchange Agent; and (c) such properly completed and executed Letter of Transmittal (or facsimile thereof), as well as the certificates representing all tendered Outstanding Notes in proper form for transfer (or a confirmation of book- entry transfer of such Outstanding Notes into the Exchange Agent's account at the Book-Entry Transfer Facility) and all other documents required by the Letter of Transmittal, are received by the Exchange Agent within five Nasdaq Stock Market trading days after the Expiration Date. 8 Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be sent to Holders who wish to tender their Outstanding Notes according to the guaranteed delivery procedures set forth above.

PARTIAL TENDERS; WITHDRAWALS. If less than the entire principal amount of Outstanding Notes evidenced by a submitted certificate is tendered, the tendering holder should fill in the principal amount tendered in the column entitled "Principal Amount Tendered" of the box entitled "Description of Notes Tendered Hereby." A newly issued Outstanding Note for the principal amount of Outstanding Notes submitted but not tendered will be sent to such holder as soon as practicable after the Expiration Date. All Outstanding Notes delivered to the Exchange Agent will be deemed to have been tendered in full unless otherwise indicated. Tenders of Outstanding Notes will be accepted only in integral multiples of $1,000. Outstanding Notes tendered pursuant to the Exchange Offer may be withdrawn at any time prior to 5:00 p.m. New York City time, on the Expiration Date, after which tenders of Outstanding Notes are irrevocable. To be effective, a written, telegraphic or facsimile transmission notice of withdrawal must be timely received by the Exchange Agent. Any such notice of withdrawal must (i) specify the name of the person having deposited the Outstanding Notes to be withdrawn (the "Depositor"), (ii) identify the Outstanding Notes to be withdrawn (including the certificate number(s) and principal amount of such Outstanding Notes, or, in the case of Outstanding Notes transferred by book-entry transfer, the name and number of the account at the Book-Entry Transfer Facility to be credited), (iii) be signed by the Holder in the same manner as the original signature on this Letter of Transmittal (including any required signature guarantees) or be accompanied by documents of transfer sufficient to have the Trustee with respect to the Outstanding Notes register the transfer of such Outstanding Notes into the name of the person withdrawing the tender, (iv) specify the name in which any such Outstanding Notes are to be registered, if different from that of the Depositor and (v) if applicable because the Outstanding Notes have been tendered pursuant to book-entry procedures, specify the name and number of the participant's account at DTC to be credited, if different from that of the Depositor. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by the Company, whose determination shall be final and binding on all parties. Any Outstanding Notes so withdrawn will be deemed not to have been validly tendered for purposes of the Exchange Offer and no Exchange Notes will be issued with respect thereto unless the Outstanding Notes so withdrawn are validly retendered. Any Outstanding Notes that have been tendered but not accepted for exchange, will be returned to the Holder thereof without cost to such Holder as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn Outstanding Notes may be retendered by following one of the procedures described above under "Procedures for Tendering" at any time prior to the Expiration Date. 4.

If any of the Outstanding Notes tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal.

If this Letter of Transmittal is signed by the registered Holder or Holders of Outstanding Notes (which term, for the purposes described herein, shall include a participant in the Book-Entry Transfer Facility whose name appears on a security listing as the holder of the Outstanding Notes) listed and tendered hereby, no endorsements of the tendered Outstanding Notes or separate written instruments of transfer or exchange are required. In any other case, the registered Holder (or acting Holder) must either properly endorse the Outstanding Notes or transmit properly completed bond powers with this Letter of Transmittal (in either case, executed exactly as the name(s) of the registered Holder(s) appear(s) on the Outstanding Notes, and, with respect to a participant in the Book-Entry Transfer Facility whose name appears on a security position listing as the owner of Outstanding Notes, exactly as the name of the participant appears on such security position listing), with the signature on the Outstanding Notes or bond power guaranteed by an Eligible Institution (except where the Outstanding Notes are tendered for the account of an Eligible Institution). If this Letter of Transmittal, any certificates or separate written instruments of transfer or exchange 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, proper evidence satisfactory to the Company of their authority so to act must be submitted. 5. SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS. Tendering Holders should indicate, in the applicable box, the name and address (or account at the Book-Entry Transfer Facility) in which the Exchange Notes or substitute Outstanding Notes for principal amounts not tendered or not accepted for exchange are to be issued (or deposited), if different from the names and addresses or accounts of the person signing this Letter of Transmittal. In the case of issuance in a different name, the employer identification number or social security number of the person named must also be indicated and the tendering Holder should complete the applicable box. If no instructions are given, the Exchange Notes (and any Outstanding Notes not tendered or not accepted) will be issued in the name of and sent to the acting Holder of the Outstanding Notes or deposited at such Holder's account at the Book-Entry Transfer Facility. 6. TRANSFER TAXES. The Company shall pay all transfer taxes, if any, applicable to the transfer and exchange of Outstanding Notes to it or its order pursuant to the Exchange Offer. If a transfer tax is imposed for any other reason other than the transfer and exchange of Outstanding Notes to the Company or its order pursuant to the Exchange Offer, the amount of any such transfer taxes (whether imposed on the registered Holder or any other person) will be payable by the tendering Holder. If satisfactory evidence of payment of such taxes or exception therefrom is not submitted herewith, the amount of such transfer taxes will be billed directly to such tendering Holder. Except as provided in this Instruction 6, it will not be necessary for transfer stamps to be affixed to the Outstanding Notes listed in this Letter of Transmittal. 7. WAIVER OF CONDITIONS.

VALIDITY AND FORM. All questions as to the validity, form, eligibility (including time of receipt), acceptance and withdrawal of Outstanding Notes tendered for exchange will be determined by the Company in its sole discretion, which determination shall be final and binding. The Company reserves the absolute right to reject any and all tenders of any Outstanding Notes not properly tendered and to reject any Outstanding Notes the Company's acceptance of which might, in the judgment of the Company or its counsel, be unlawful. The Company also reserves the absolute right at its sole discretion to waive any defects or irregularities or conditions of the Exchange Offer as to any particular Outstanding Notes either before or after the Expiration Date (including the right to waive the ineligibility of any holder who seeks to tender Outstanding Notes in the Exchange Offer). The interpretation of the terms and conditions of the Exchange Offer as to any Outstanding Notes either before or after the Expiration Date (including the Letter of Transmittal and the instructions thereto) by the Company shall be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Outstanding Notes for exchange must be cured within such period of 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 any defects or irregularities with respect to any tender of Outstanding Notes for exchange, nor shall any of them incur any liability for failure to give such notification. Tenders of the Outstanding Notes will not be deemed to have been made until such irregularities have been cured or waived. 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, unless otherwise provided in the Letter of Transmittal, as soon as practicable following the Expiration Date. IMPORTANT TAX INFORMATION Under federal income tax law, a Holder tendering Outstanding Notes is required to provide the Exchange Agent with such holder's correct TIN on Substitute Form W-9 below. If such Holder is an individual, the TIN is the Holder's social security number. The Certificate of Awaiting Taxpayer Identification Number should be completed if the tendering Holder has not been issued a TIN and has applied for a number or intends to apply for a number in the near future. If the Exchange Agent is not provided with the correct TIN, the Holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, payments that are made to such Holder with respect to tendered Outstanding Notes may be subject to backup withholding. Certain Holders (including, among others, all corporations and certain foreign individuals and foreign entities) are not subject to these backup withholding and reporting requirements. In order for such a Holder to qualify as an exempt recipient, that holder must submit to the Exchange Agent a properly completed Internal Revenue Service Form W-8, signed under penalties of perjury, attesting to that Holder's exempt status. Such forms can be obtained from the Exchange Agent. If backup withholding applies, the Exchange Agent is required to withhold 31% of any amounts otherwise payable to the Holder. Backup withholding is not an additional tax. Rather, the 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. 11 PURPOSE OF SUBSTITUTE FORM W-9 To prevent backup withholding on payments that are made to a Holder with respect to Outstanding Notes tendered for exchange, the Holder is required to notify the Exchange Agent of his or her correct TIN by completing the form herein certifying that the TIN provided on Substitute Form W-9 is correct (or that such Holder is awaiting a TIN) and that (i) such Holder has not been notified by the Internal Revenue Service that he or she is subject to backup withholding as a result of failure to report all interest or dividends or (ii) the Internal Revenue Service has notified such Holder that he or she is no longer subject to backup withholding. WHAT NUMBER TO GIVE THE EXCHANGE AGENT Each Holder is required to give the Exchange Agent the social security number or employer identification number of the record Holder(s) of the Outstanding Notes. If Outstanding Notes are in more than one name or are not in the name of the actual Holder, consult the instructions on Internal Revenue Service Form W- 9, which may be obtained from the Exchange Agent, for additional guidance on which number to report. CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER If the tendering holder has not been issued a TIN and has applied for a number or intends to apply for a number in the near future, write "Applied For" in the space for the TIN on Substitute Form W-9, sign and date the form and the Certificate of Awaiting Taxpayer Identification Number and return them to the Exchange Agent. If such certificate is completed and the Exchange Agent is not provided with the TIN within 60 days, the Exchange Agent will withhold 31% of all payments made thereafter until a TIN is provided to the Exchange Agent. IMPORTANT: THIS LETTER OF TRANSMITTAL OR A MANUALLY SIGNED FACSIMILE THEREOF (TOGETHER WITH OUTSTANDING NOTES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR A NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO THE EXPIRATION DATE. 12 Name (if joint names, list first and circle the name of the person or entity whose number you enter in Part 1 below.
