WHEREAS, immediately after giving effect to the Merger, no Default or Event of Default existed and thus the Merger was effected in accordance with Section 10.03 of the Indenture;

WHEREAS, all acts and things necessary to make this Third Supplemental Indenture a valid and legally binding agreement according to its terms, and a valid and legally binding amendment of and supplement to, the Indenture, have been duly done and performed;

NOW, THEREFORE, to comply with the provisions of the Indenture and in consideration of the above premises, the Issuers, the Guarantors, the New Guarantor and the Trustee covenant and agree for the equal and proportionate benefit of the respective Holders of the Notes as follows:
