ARTICLE IV. LIMITATION ON DIRECTORS LIABILITY

A director of the Corporation shall not be personally liable to the Corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, except for

(i) liability based on a breach of the duty of loyalty to the Corporation or the shareholders;

(ii) liability for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law; (iii) liability based on the payment of an improper dividend or an improper repurchase of the Corporation’s stock under Minnesota Statutes Section 302A.559 or on violations of Minnesota state securities laws (Minnesota Statutes, Section 80A.23);

(iv) liability for any transaction from which the director derived an improper personal benefit; or

(v) liability for any act or omission occurring prior to the date this Article IV becomes effective. If the Minnesota Business Corporation Act is hereafter amended to authorize the further elimination or limitation of the liability of directors, then the liability of a director of the Corporation, in addition to the limitation on personal liability provided herein, shall be limited to the fullest extent permitted by the amended Minnesota Business Corporation Act. Any repeal or modification of this Article by the shareholders of the Corporation shall be prospective only, and shall not adversely affect any limitation on the personal liability of a director of the Corporation existing at the time of such repeal or modification. The provisions of this Article IV shall not be deemed to limit or preclude indemnification of a director by this Corporation for any liability of a director which has not been eliminated by the provisions of this Article IV.

The foregoing restated Articles of Incorporation supersede the original Articles of Incorporation and all amendments to them.

I swear that the foregoing is true and accurate and that I have authority to sign these Articles of Amendment on behalf of the Corporation.
