If the undersigned or the person receiving the new bonds covered by this letter is an affiliate (as defined under Rule 405 of the Securities Act) of the Company, the undersigned represents to the Company that the undesigned understands and acknowledges that such new bonds may not be offered for resale, resold or otherwise transferred by the undersigned or such other person without registration under the Securities Act or an exemption therefrom.

DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES. All physically delivered old bonds or confirmations of any book-entry transfer to the Exchange Agent's account at a book-entry transfer facility of old bonds tendered by book- entry transfer, as well as a properly completed and duly executed copy of this Letter of Transmittal or facsimile thereof, and any other documents required by this Letter of Transmittal, must be received by the Exchange Agent at the address set forth herein on or prior to the Expiration Date (as defined in the Prospectus). The method of delivery of this Letter of Transmittal, the old bonds and any other required documents is at the election and risk of the Holder, and except as otherwise provided below, the delivery will be deemed made only when actually received by the Exchange Agent. If such delivery is by mail, it is suggested that registered mail with return receipt requested, properly insured, be used. No alternative, conditional, irregular or contingent tenders will be accepted. All tendering Holders, by execution of this Letter of Transmittal (or facsimile thereof), shall waive any right to receive notice of the acceptance of the old bonds for exchange. Delivery to an address other than as set forth herein, or instructions via a facsimile number other than the ones set forth herein, will not constitute a valid delivery. 2. GUARANTEED DELIVERY PROCEDURES. Holders who wish to tender their old bonds, but whose old bonds are not immediately available and thus cannot deliver their old bonds, the Letter of Transmittal or any other required documents to the Exchange Agent (or comply with the procedures for book-entry transfer) on or 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 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 registration number(s) of such old bonds and the principal amount of old bonds tendered, stating that the tender is being made thereby and guaranteeing that, within three New York Stock Exchange trading days after the Expiration Date, the Letter of Transmittal (or facsimile thereof), together with the old bonds (or a confirmation of book-entry transfer of such old bonds into the Exchange Agent's account at the Depository) 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 all tendered old bonds in proper form for transfer (or a confirmation of book-entry transfer of such old bonds into the Exchange Agent's account at the Depository) and all other documents required by the Letter of Transmittal, are received by the Exchange Agent within three New York Stock Exchange trading days after the Expiration Date. Any Holder who wishes to tender old bonds pursuant to the guaranteed delivery procedures described above must ensure that the Exchange Agent receives the Notice of Guaranteed Delivery relating to such old bonds prior to the Expiration Date. Failure to complete the guaranteed delivery procedures outlined above will not, of itself, affect the validity or effect a revocation of any Letter of Transmittal form properly completed and executed by a Holder who attempted to use the guaranteed delivery procedures. 3. PARTIAL TENDERS; WITHDRAWALS. If less than the entire principal amount of old bonds 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 Old Bonds Tendered Hereby." A newly issued old bond for the principal amount of old bonds submitted but not tendered will be sent to such Holder as soon as practicable after the Expiration Date. All old bonds delivered to the Exchange Agent will be deemed to have been tendered in full unless otherwise indicated. 8 Old bonds tendered pursuant to the Exchange Offer may be withdrawn at any time prior to the Expiration Date, after which tenders of old bonds 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 old bonds to be withdrawn (the "Depositor"), (ii) identify the old bonds to be withdrawn (including the registration number(s) and principal amount of such old bonds or, in the case of old bonds transferred by book-entry transfer, the name and number of the account at the Depository 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 Medallion Guarantees) or be accompanied by documents of transfer sufficient to have the Trustee with respect to the old bonds register the transfer of such old bonds into the name of the person withdrawing the tender and (iv) specify the name in which any such old bonds are to be registered, 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 old bonds so withdrawn will be deemed not to have been validly tendered for purposes of the Exchange Offer and no new bonds will be issued with respect thereto unless the old bonds so withdrawn are validly retendered. Any old bonds which have been tendered but which are not accepted for exchange, will be returned to the Holder thereof without cost to such Holder, or will be credited to an account maintained with the Depository, as soon as practicable after withdrawal, rejection of tender or termination of Exchange Offer. 4. SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND ENDORSEMENTS; MEDALLION GUARANTEE. If this Letter of Transmittal is signed by the registered Holder(s) of the old bonds tendered hereby, the signature must correspond with the name(s) as written on the face of the certificates without alteration or enlargement or any change whatsoever. If this Letter of Transmittal is signed by a participant in the Depository, the signature must correspond with the name as it appears on the security position listing as the owner of the old bonds. If any of the old bonds tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal. If a number of old bonds registered in different names is tendered, it will be necessary to complete, sign and submit as many separate copies of this Letter of Transmittal as there are different registrations of old bonds. Signatures on this Letter of Transmittal or on a notice of withdrawal, as the case may be, must be Medallion Guaranteed by an Eligible Institution unless the old bonds tendered hereby are tendered (i) by a registered Holder who has not completed the box entitled "Special Registration Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or (ii) for the account of an Eligible Institution. If this Letter of Transmittal is signed by the registered Holder or Holders of old bonds (which term, for the purposes described herein, shall include a participant in the Depository whose name appears on a security listing as the owner of the old bonds) listed and tendered hereby, no endorsements of the tendered old bonds 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 old bonds 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 old bonds, and, with respect to a participant in the Depository whose name appears on a security position listing as the owner of old bonds, exactly as the name of the participant appears on such security position listing), with the signature on the old bonds or bond power guaranteed by an Eligible Institution (except where the old bonds 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 to so 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 Depository) in which the new bonds or substitute old bonds 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 9 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 new bonds (and any old bonds not tendered or not accepted) will be issued in the name of and sent to the acting Holder of the old bonds or deposited at such Holder's account at the Depository. 6. TRANSFER TAXES. The Company shall pay all transfer taxes, if any, applicable to the transfer and exchange of old bonds 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 old bonds 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 collected from the tendering Holder by the Exchange Agent. Except as provided in this Instruction 6, it will not be necessary for transfer stamps to be affixed to the old bonds listed in this Letter of Transmittal. 7. WAIVER OF CONDITIONS. The Company reserves the right, in its reasonable judgment, to waive, in whole or in part, any of the conditions to the Exchange Offer set forth in the Prospectus. 8. MUTILATED, LOST, STOLEN OR DESTROYED OLD BONDS. Any Holder whose old bonds have been mutilated, lost, stolen or destroyed should contact the Exchange Agent at the address indicated above for further instructions. 9.

VALIDITY AND FORM. All questions as to the validity, form, eligibility (including time of receipt), acceptance of tendered old bonds and withdrawal of tendered old bonds 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 old bonds not properly tendered or any old bonds the Company's acceptance of which would, in the opinion of counsel for the Company, be unlawful. The Company also reserves the right, in its reasonable judgment, to waive any defects, irregularities or conditions of tender as to particular old bonds. The Company's interpretation of the terms and conditions of the Exchange Offer (including the instructions in this Letter of Transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of old bonds must be 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 old bonds, neither the Company, the Exchange Agent nor any other person shall incur any liability for failure to give such notification. Tenders of old bonds will not be deemed to have been made until such defects or irregularities have been cured or waived. Any old bonds 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 Holder as soon as practicable following the Expiration Date. 10 IMPORTANT TAX INFORMATION Under federal income tax law, a Holder tendering old bonds is required to provide the Exchange Agent with such Holder's correct TIN on the Substitute Form W-9 above. 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 old bonds may be subject to backup withholding of 28%. Certain Holders (including, among others, all domestic corporations) are not subject to these backup withholding and reporting requirements. See the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional instructions. If backup withholding applies, the Exchange Agent is required to withhold 28% 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. PURPOSE OF SUBSTITUTE FORM W-9 To prevent backup withholding on payments that are made to a Holder with respect to old bonds 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 the Holder is not subject to backup withholding because either (i) each Holder is exempt from backup withholding, (ii) 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 (iii) the Internal Revenue Service has notified such Holder that he or she is no longer subject to backup withholding and that the Holder is a U.S. person. 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 old bonds. If old bonds are in more than one name or are not in the name of the actual Holder, consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional guidance on which number to report. 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, the Holder should write "Applied For" in the space provided for the TIN in Part I, and sign and date the Substitute Form W-9. If "Applied For" is written in Part I and the Depositary is not provided with a TIN within 60 days, the Depositary will withhold 28% of all payments of the purchase price to such stockholder until a TIN is provided to the Depositary. IMPORTANT: THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF (TOGETHER WITH OLD BONDS 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. 11
