NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Subsequent Guarantors, the Company, the Trustee and the EUR Agent mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:
