referred to herein.

8.

Miscellaneous.  The provisions of this Amendment shall inure to the benefit of
any holder of any Note, and shall inure to the benefit of and be binding upon

making of the loans under the Credit Agreement, as so amended.  This Amendment
shall be governed by and construed in accordance with the internal laws of the
State of Wisconsin.  This Amendment may be signed in any number of counterparts
with the same effect as if the signatures thereto and hereto were upon the same
