New Castle’s termination does not affect any of its obligations which, pursuant
to said Agreement, are intended to survive the termination.
Kindly countersign below to indicate your assent to the foregoing and our mutual
agreement to terminate the Agreement effective as of the date of this letter.

            Very truly yours,
