We are requesting that you contact your clients for whom you hold Outstanding Notes regarding the Exchange Offer. For your information and for forwarding to your clients for whom you hold Outstanding Notes registered in your name or in the name of your nominee, or who hold Outstanding Notes registered in their own names, we are enclosing the following documents:

1. Prospectus, dated                     , 2010;

2. The Letter of Transmittal for your use and for the information of your clients;

3. A Notice of Guaranteed Delivery to be used to accept the Exchange Offer if certificates for Outstanding Notes are not immediately available or time will not permit all required documents to reach the Exchange Agent prior to the Expiration Date (as defined below) or if the procedure for book-entry transfer cannot be completed on a timely basis;

4. A form of letter which may be sent to your clients for whose account you hold Outstanding Notes registered in your name or the name of your nominee, with space provided for obtaining such clients’ instructions with regard to the Exchange Offer; and

5. Return envelopes addressed to U.S. Bank National Association, the Exchange Agent for the Exchange Offer.

YOUR PROMPT ACTION IS REQUESTED. THE EXCHANGE OFFER WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY TIME, ON                     , 2010, UNLESS EXTENDED BY THE COMPANY (THE “EXPIRATION DATE”).

If a registered holder of Outstanding Notes desires to tender Outstanding Notes, but such Outstanding Notes are not immediately available, or time will not permit such holder’s Outstanding Notes or other required documents to reach the Exchange Agent before the Expiration Date, or the procedure for book-entry transfer cannot be completed on a timely basis, a tender may be effected by following the guaranteed delivery procedures described in the Prospectus under the caption “The Exchange Offer—Procedures for Tendering.”

The Company will, upon request, reimburse brokers, dealers, commercial banks and trust companies for reasonable and necessary costs and expenses incurred by them in forwarding the Prospectus and the related documents to the beneficial owners of Outstanding Notes held by them as nominee or in a fiduciary capacity. The Company will pay or cause to be paid all stock transfer taxes applicable to the exchange of Outstanding Notes pursuant to the Exchange Offer, except as set forth in Instruction 5 of the Letter of Transmittal.

Any inquiries you may have with respect to Exchange Offer, or requests for additional copies of the enclosed materials, should be directed to U.S. Bank National Association, the Exchange Agent for the Exchange Offer, at its address and telephone number set forth on the front of the Letter of Transmittal.
