     WHEREAS, the Trustee is willing to enter into the Indenture, but only upon the condition, among others, that the Grantor shall have executed and delivered to the Trustee, for the benefit of the Noteholders, that certain Security Agreement dated as of September 9, 2004 (including all annexes, exhibits or schedules thereto, as from time to time amended, restated, supplemented or otherwise modified, the “Security Agreement”); and

     WHEREAS, pursuant to the Security Agreement, the Grantor is required to execute and deliver to the Trustee, for the benefit of the Noteholders, this Trademark Security Agreement.

     NOW, THEREFORE, in consideration of the premises and mutual covenants herein contained and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Grantor hereby agrees as follows:

     1. DEFINED TERMS. All capitalized terms used but not otherwise defined herein have the meanings given to them in the Security Agreement.

     2. GRANT OF SECURITY INTEREST IN TRADEMARK COLLATERAL. The Grantor hereby grants to the Trustee, for the benefit of the Noteholders, a continuing security interest in all of the Grantor’s right, title and interest in, to and under the following, whether presently existing or hereafter created or acquired (collectively, the “Trademark Collateral”):

          (a) all of its Trademarks and Trademark Intellectual Property Licenses to which it is a party including those referred to on Schedule I hereto;

          (b) all renewals of the foregoing;

          (c) all goodwill of the business connected with the use of, and symbolized by, each Trademark and each Trademark Intellectual Property License; and
