Amendment and Restatement of Articles of Incorporation
If the proposed amendment is approved, Articles 1, 3 and 8 of our current Articles of Incorporation would incorporate certain stylistic, clarifying and conforming changes. In addition, the Restated Articles of Incorporation would integrate into a single document the operative provisions of the Articles of Merger and previous amendments to the Articles of Incorporation, which were filed with the Secretary of State of Minnesota on March 1, 2000, May 14, 2001, and May 24, 2005, respectively, and the elimination of several series of preferred stock, none of which are currently outstanding. The proposed amendment is reflected in the marked copy of the proposed form of Restated Articles of Incorporation attached to this proxy statement as Appendix A.
