Section headings in this Amendment are included herein for convenience of reference only and shall not constitute part of this Amendment for any other purpose.

Nothing in this Amendment shall be construed to alter the existing debtor-creditor relationship between the Issuer and the Guarantors, on the one hand, and the Forbearing Noteholders, on the other hand.
