The terms of the Exchange Notes are identical in all material respects (including principal amount, interest rate and maturity) to the terms of the Old Notes for which they may be exchanged pursuant to the Exchange Offer, except that the Exchange Notes are freely transferable by holders thereof, upon the terms and subject to conditions set forth in the enclosed Prospectus. The Issuer will accept for exchange any and all Old Notes properly tendered according to the terms of the Prospectus and the Letter of Transmittal. Consummation of the Exchange Offer is subject to certain conditions described in the Prospectus.

WE URGE YOU TO PROMPTLY CONTACT YOUR CLIENTS FOR WHOM YOU HOLD OLD NOTES REGISTERED IN YOUR NAME OR IN THE NAME OF YOUR NOMINEE OR WHO HOLD OLD NOTES REGISTERED IN THEIR OWN NAMES. PLEASE NOTE THAT THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON                     , 2011, UNLESS THE ISSUER EXTENDS THE EXCHANGE OFFER (SUCH DATE AND TIME, AS IT MAY BE EXTENDED, THE “EXPIRATION DATE”).

The Issuer will not pay any fees or commissions to you for soliciting tenders of Old Notes pursuant to the Exchange Offer. The Issuer will pay all transfer taxes, if any, applicable to the tender of Old Notes to it or its order, except as otherwise provided in the Prospectus and the Letter of Transmittal.

The Letter of Transmittal for your use in connection with the tender of Old Notes and for the information of your clients, including a Substitute Form W-9 and Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 (providing information relating to U.S. federal income tax backup withholding).

3. A form of Notice of Guaranteed Delivery.

4. A form of letter which you may send, as a cover letter to accompany the Prospectus and related materials, to your clients for whose accounts you hold Old Notes registered in your name or the name of your nominee, with space provided for obtaining the client’s instructions regarding the Exchange Offer.

Your prompt action is requested. Tendered Old Notes may be withdrawn, subject to the procedures described in the Prospectus, at any time prior to 5:00 p.m., New York City time, on the Expiration Date.
