(the “Companies”) to exchange $650,000,000 aggregate principal amount of our 10% senior notes due 2014 and the guarantees thereof, €150,000,000 aggregate principal amount of our 9% senior notes due 2014 and the guarantees thereof, and $1,070,000,000 aggregate principal amount at maturity of our 12 ¹/2% senior subordinated discount notes due 2016 and the guarantees thereof, (the “New Notes”), which have been registered under the Securities Act of 1933, as amended, for any and all outstanding unregistered 10% senior notes due 2014 and the guarantees thereof, 9% senior notes due 2014 and the guarantees thereof, and 12 ¹/2% senior subordinated discount notes due 2016 and the guarantees thereof (the “Old Notes”) issued on August 9, 2006, upon the terms and subject to the conditions described in the Prospectus. The Exchange Offers are being made in order to satisfy certain of our obligations contained in the Registration Rights Agreements dated as of August 9, 2006 among us and the Initial Purchasers named therein (the “Registration Rights Agreements”). As set forth in the Prospectus, the terms of the New

Notes are identical in all material respects to the Old Notes, except that the New Notes have been registered under the Securities Act and therefore will not be subject to certain restrictions on their transfer and will not contain certain provisions providing for an increase in the interest rate thereon under the circumstances set forth in the Registration Rights Agreements described in the Prospectus. Old Notes may be tendered in a principal amount of $2,000 and integral multiples of $1,000, for dollar-denominated Old Notes and €2,000 and integral multiples of €1,000, for euro-denominated Old Notes.

The Exchange Offers are subject to certain conditions. See “The Exchange Offer—Conditions to the Exchange Offer” in the Prospectus.

1. the Prospectus, dated July         , 2007;

2. a form of letter which may be sent to your clients for whose accounts you hold Old Notes registered in your name or in the name of your nominee, with space provided for obtaining such clients’ instructions with regard to the Exchange Offers; and

Your prompt action is requested. Please note the Exchange Offers for dollar-denominated Old Notes will expire at 5:00 P.M., New York City time, on August     , 2007, unless extended, and the Exchange Offer for euro-denominated Old Notes will expire at 5:00 P.M., London time, on August     , 2007, unless extended. Please furnish copies of the enclosed materials to those of your clients for whom you hold Old Notes registered in your name or in the name of your nominee as quickly as possible. The Old Notes tendered pursuant to the Exchange Offers may be withdrawn at any time before the related expiration times.

In all cases, exchanges of Old Notes pursuant to the Exchange Offers will be made only after timely receipt by the exchange agent (as defined in the Prospectus) of (a) a book-entry confirmation (as defined in the Prospectus), as the case may be and (b) any other required documents.

Holders who wish to tender their Old Notes and who cannot deliver an agent’s message and any other documents required by the Prospectus to the exchange agent prior to 5:00 P.M., New York City time, on August , 2007 (unless extended) must tender their Old Notes according to the procedures set forth under the caption “The Exchange Offers—Procedures for Tendering Old Notes—How to Tender Notes Held Through DTC” and “The Exchange Offers—Procedures for Tendering Old Notes—How to Tender Notes Held Through Euroclear and Clearstream” in the Prospectus.

We are not making the Exchange Offers to, nor will we accept tenders from or on behalf of, holders of Old Notes residing in any jurisdiction in which the making of the Exchange Offers or the acceptance of tenders would not be in compliance with the laws of such jurisdiction.

We will not make any payments to brokers, dealers or other persons for soliciting acceptances of the Exchange Offers. We will, however, upon request, reimburse you for customary clerical and mailing expenses incurred by you in forwarding any of the enclosed materials to your clients. We will pay or cause to be paid any transfer taxes payable on the transfer of Old Notes to us, except as otherwise provided in the Prospectus.
