I have also examined originals or copies, certified or otherwise identified to my satisfaction, of such records of the Company and such agreements, certificates of public officials, certificates of officers or other representatives of the Company and others, and such other documents, certificates and records as I have deemed necessary or appropriate as a basis for the opinions set forth below.

In my examination, I have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to me as facsimile, electronic, certified, conformed or photostatic copies and the authenticity of the originals of such latter documents. In making my examination of documents executed or to be executed, I have assumed that the parties thereto, other than the Company, had or will have the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents, and the validity and binding effect thereof. As to any facts material to the opinions expressed herein which we have not independently established or verified, I have relied upon statements and representations of officers and other representatives of the Company, public officials and others.

My opinion set forth herein is limited to the laws of the State of Wisconsin which are normally applicable to transactions of the type contemplated by the Exchange Offer (the “Opined on Law”). I do not express any opinion with respect to the laws of any other jurisdiction other than the Opined on Law or as to the effect of any such non-opined on law on the opinions herein stated. I am a member of the Bar in the State of Wisconsin.

Based upon and subject to the foregoing limitations, qualifications, exceptions and assumptions set forth herein, I am of the opinion that the Exchange Notes have been duly and validly authorized by the Company.

I hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement.

Very truly yours,
