In such capacity, we have examined, among other documents, the Certificate of Incorporation of the Company, as amended, the By-Laws of the Company, as amended, and the Registration Statement on Form S-8 to be filed by the Company with the Securities and Exchange Commission on or shortly after the date of this letter covering the offering of the Company's Common Stock pursuant to the Plan. Based on the foregoing and such additional investigation as we have deemed necessary, it is our opinion that the shares of Common Stock to be offered under the Plan have been duly authorized under the Certificate of Incorporation of the Company and the laws of the State of Delaware. When issued and paid for in accordance with the description set forth in the Registration Statement and the Plan, the Common Stock will be validly issued, fully-paid, and non-assessable, except as set forth in Wisconsin Statutes Section 180.0622(2)(b) as judicially interpreted.
