The additional shares of Common Stock and the Rights subject to the Registration Statement relate to an amendment of the Plan adopted by the Board of Directors and approved by the shareholders of the Company that increased the aggregate number of shares issuable thereunder from 2,500,000 to 5,000,000. The terms of the Rights issuable under the Plan are as set forth in that certain Rights Agreement (the "Rights Agreement"), dated as of October 29, 1991, by and between the Company and First Wisconsin Trust Company (n/k/a Firstar Bank, N.A.). In connection with our opinion as set forth below, we have examined: (i) the Plan; (ii) signed copies of the Registration Statement; (iii) the Company's Restated Articles of Incorporation and By-Laws, as amended to date; (iv) the Rights Agreement; (v) corporate proceedings of the Company relating to the adoption of the above-described amendment to the Plan and the issuance of additional shares of Common Stock and Rights thereunder; and (vi) such other proceedings, documents and records as we have deemed necessary to enable us to render this opinion. Foley & Lardner Banta Corporation August 29, 2001 Page 2 Based on the foregoing, we are of the opinion that: 1. The Company is a corporation validly existing under the laws of the State of Wisconsin. 2. The Common Stock subject to the Registration Statement, when issued and paid for in the manner provided in the Plan, will be validly issued, fully paid and nonassessable and no personal liability will attach to the ownership thereof, except with respect to wage claims of employees of the Company for services performed, not to exceed six months' service in any one case, as provided in Section 180.0622(2)(b) of the Wisconsin Business Corporation Law and judicial interpretations thereof. 3. The Rights subject to the Registration Statement, when issued pursuant to the terms of the Rights Agreement, will be validly issued. We consent to the use of this opinion as an exhibit to the Registration Statement. In giving our consent, we do not admit that we are "experts" within the meaning of Section 11 of the Securities Act, or within the category of persons whose consent is required by Section 7 of said Act.
