the Indenture, such latter provision shall control.  If any provision of the
Indenture, as supplemented by this First Supplemental Indenture, modifies or
excludes any provision of the Trust Indenture Act that may be so modified or

modified or to be excluded, as the case may be.

Supplemental Indenture have been inserted for convenience of reference only,
are not to be considered a part hereof and shall in no way modify or restrict
any of the terms or provisions hereof.

enforceability of the remaining provisions hereof or of the Indenture shall
not in any way be affected or impaired thereby.
