The undersigned hereby irrevocably constitutes and appoints the Exchange Agent as the true and lawful agent and attorney in fact of the undersigned with respect to the Tendered Notes, with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (i) deliver the Tendered Notes to the Company or cause ownership of the Tendered Notes to be transferred to, or upon the order of, the Company, and deliver all accompanying evidences of transfer and authenticity to, or upon the order of, the Company upon receipt by the Exchange Agent, as the undersigned's agent, of the New Notes to which the undersigned is entitled upon the acceptance by the Company of the Tendered Notes pursuant to the Exchange Offer, and (ii) receive all benefits and otherwise exercise all rights of beneficial ownership of the Tendered Notes, all in accordance with the terms of the Exchange Offer. The undersigned also acknowledges that this Exchange Offer is being made by the Company in reliance on an interpretation by the staff of the Securities and Exchange Commission (the "Commission"), as set forth in certain no-action letters to third parties, that the New Notes issued in exchange for the Old Notes pursuant to the Exchange Offer may be offered for resale, resold and otherwise transferred by holders thereof (other than a broker-dealer, as set forth below, or any such holder that is an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act of 1933, as amended (the "Securities Act"), without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such New Notes are acquired in the ordinary course of such holder's business and such holders have no arrangement with any person to participate in the distribution (within the meaning of the Securities Act) of such New Notes. By tendering, each holder of Old Notes represents to the Company that (i) the New Notes or Book-Entry Interests therein to be acquired by such holder and any beneficial owner(s) of such Old Notes or interests therein ("Beneficial Owner(s)") in connection with the Exchange Offer are being acquired by such holder and any Beneficial Owner(s) in the ordinary course of business of the holder and any Beneficial Owner(s), (ii) the holder and each Beneficial Owner are not participating, do not intend to participate, and have no arrangement or understanding with any person to participate, in the distribution of the New Notes, (iii) if the holder is a resident of the State of California, it falls under the self-executing institutional investor exemption set forth under Section 25102(i) of the Corporate Securities Law of 1968 and Rules 260.102.10 and 260.105.14 of the California Blue Sky Regulations, (iv) if the undersigned is a resident of the Commonwealth of Pennsylvania, it falls under the self-executing institutional investor exemption set forth under Sections 203(c), 102(d) and (k) of the Pennsylvania Securities Act of 1972, Section 102.111 of the Pennsylvania Blue Sky Regulations and an interpretive opinion dated November 16, 1985, (v) the holder and each Beneficial Owner acknowledge and agree that any person who is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or is participating in the Exchange Offer for the purpose of distributing the New Notes must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction of the New Notes or interests therein acquired by such person and cannot rely on the position of the staff of the Commission set forth in certain no-action letters, (vi) the holder and each Beneficial Owner understands that a secondary resale transaction described in clause (v) above and any resales of New Notes or interests therein obtained by such holder in exchange for Old Notes or interests therein originally acquired by such holder directly from the Company should be covered by an effective registration statement containing the selling security holder information required by Item 507 or Item 508, as applicable, of Regulation S-K of the Commission and (vii) neither the holder nor any Beneficial Owner(s) is an "affiliate," as defined in Rule 405 under the Securities Act, of the Company. Upon a request by the Company, a holder or beneficial owner will deliver to the Company a legal opinion confirming its representation made in clause (vii) above.

All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned and any Beneficial Owner(s), and every obligation of the undersigned or any Beneficial Owners hereunder shall be binding upon the heirs, representatives, successors, and assigns of the undersigned and such Beneficial Owner(s).

Beneficial Owner Instructions to Registered Holders. Only a holder in whose name Definitive Registered Notes are registered on the books of the registrar (or the legal representative or attorney-in-fact of such registered holder) or who is a DTC participant who owns a Book-Entry Interest in the Old Notes through a security position maintained by DTC may execute and deliver this Letter of Transmittal.

If this Letter of Transmittal is signed by the DTC participant whose name appears on a security position maintained by DTC (in the case of Book-Entry Interests), the signature must correspond exactly with such participant's name as it appears on a security position maintained by DTC listing such participant as the owner of the Old Notes, without any change whatsoever. If any of the Tendered Notes are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal. If any Tendered Notes are held in different names on several Old Notes, it will be necessary to complete, sign, and submit as many separate copies of the Letter of Transmittal documents as there are names in which Tendered Notes are held. When this Letter of Transmittal is signed by the holders of the Old Notes specified herein and tendered hereby, no separate bond powers are required. If, however, the New Notes are to be issued, or any untendered or unaccepted Old Notes are to be reissued, to a person other than the holder, then separate bond powers are required. Signatures on such bond powers must be guaranteed by an Eligible Institution. If this Letter of Transmittal or any Old Notes 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.

Transfer Taxes. The Company will pay all transfer taxes, if any, applicable to the sale and transfer of Old Notes to it or its order pursuant to the Exchange Offer. If, however, a transfer tax is imposed for any reason other than the transfer and sale of Old Notes to the Company or its order pursuant to the Exchange Offer, then the amount of any such transfer taxes (whether imposed on the registered holder or on any other person) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption from taxes therefrom is not submitted with this Letter of Transmittal, the amount of transfer taxes will be billed directly to such tendering holder. 8.
