As used in this letter, the “Existing Notes” refers to the Existing 10% Senior Notes and the Existing 11.75% Senior Subordinated PIK Notes collectively, the “Exchange Notes” refers to the Exchange 10% Senior Notes and the Exchange 11.75% Senior Subordinated PIK Notes collectively, and the “Notes” refers to the Existing Notes and the Exchange Notes, collectively. The Prospectus and the Letter of Transmittal together constitute the “Exchange Offer”.

As set forth in the Prospectus, the terms of the Exchange Notes are identical in all material respects to the Existing Notes, except that the Exchange Notes (i) have been registered under the Securities Act, and therefore will not bear legends restricting their transfer, (ii) are not entitled to registration rights of which the Existing Notes are entitled under the Registration Rights Agreements, dated as of October 15, 2009, among the Issuers, the dealer managers with respect to the initial issuances of the Existing Notes and the guarantors of the Existing Notes set forth on Annex I thereto (the “Registration Rights Agreements”), and (iii) will not contain certain provisions providing for the payment of additional interest to the holders of the Existing Notes under certain circumstances relating to the registration and consummation of the Exchange Offer.

Accordingly, we request instructions as to whether you wish us to exchange any or all Existing Notes held by us for your account or benefit, pursuant to the terms and conditions set forth in the Prospectus and Letter of Transmittal. We urge you to carefully read the Prospectus and Letter of Transmittal before instructing us to exchange your Existing Notes.

Your instructions to us should be forwarded as promptly as possible to permit us to exchange Existing Notes on your behalf in accordance with the provisions of the Exchange Offer.
