The terms of the Exchange Notes are substantially identical (including principal amount, interest rate and maturity) to the terms of the Outstanding Notes for which they may be exchanged pursuant to the Exchange Offers, except that the Exchange Notes are freely transferable by holders thereof, upon the terms and subject to conditions set forth in the enclosed Prospectus, and the registration rights and additional interest provisions relating to the Outstanding Notes will not apply to them. The Outstanding Notes are guaranteed on a senior unsecured basis (the “Old Guarantees”) by the Guarantors, and the Exchange Notes will be guaranteed on a senior unsecured basis (the “New Guarantees”) by the Guarantors. Upon the terms and subject to the conditions set forth in the Prospectus and the Letter of Transmittal, the Guarantors offer to issue the New Guarantees with respect to all Exchange Notes issued in the Exchange Offers in exchange for the Old Guarantees of the Outstanding Notes for which such Exchange Notes are issued in the Exchange Offers. Throughout this letter, unless the context otherwise requires and whether so expressed or not, references to the “Exchange Offers” include the Guarantors’ offers to exchange the New Guarantees for the Old Guarantees, references to the “Exchange Notes” include the related New Guarantees and references to the “Outstanding Notes” include the related Old Guarantees. The Issuer will accept for exchange any and all Outstanding Notes properly tendered according to the terms of the Prospectus and the Letter of Transmittal. Consummation of the Exchange Offers is subject to certain conditions described in the Prospectus.

This material is being forwarded to you as the beneficial owner of Outstanding Notes held by us for your account but not registered in your name.

If we do not receive written instructions in accordance with the below and the procedures presented in the Prospectus and the Letter of Transmittal, we will not tender any of the Outstanding Notes in your account. We urge you to read the Prospectus and the Letter of Transmittal carefully before instructing us as to whether or not to tender your Outstanding Notes.
