WHEREAS, in
accordance with the terms of the Indenture, the Company is entering into this

claim based on, in respect of, or by reason of, such obligations or their
creation. Each Holder by accepting Notes waives and releases all such liability.

Supplemental Indenture limits, qualifies, or conflicts with any provision of
the Trust Indenture Act of 1939, as amended (the “Act”), that is
required under such Act to be part of and govern any provision of this
Supplemental Indenture, the provision of such Act shall control. If any
provision of this Supplemental Indenture modifies or excludes any provision of
