<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">The Company is incorporated in Wisconsin and is
governed by the Wisconsin Business Corporation Law (the &ldquo;<U>WBCL</U>&rdquo;). The WBCL includes provisions providing for indemnification
by a corporation of a director or officer against certain liabilities and expenses incurred by him or her in any proceeding (whether threatened,
pending, or completed, and whether brought by the Company or any other person) to which he or she was a party because of being a director
or officer. Under Section&nbsp;180.0851(1)&nbsp;of the WBCL, the Company is required to indemnify a director or officer, to the extent
such person is successful on the merits or otherwise in the defense of a proceeding, for all reasonable expenses incurred in the proceeding
if such person was a party because he or she was a director or officer of the Company. In all other cases, the Company is required by
Section&nbsp;180.0851(2)&nbsp;of the WBCL to indemnify a director or officer against liabilities (including, among other things, judgments,
penalties, fines and reasonable expenses) incurred in a proceeding to which such person was a party because he or she was an officer or
director of the Company, unless liability was incurred because he or she breached or failed to perform a duty to which he or she owes
the Company and the breach or failure constitutes any of the following: (i)&nbsp;a willful failure to deal fairly with the Company or
its shareholders in connection with a matter in which he or she has a material conflict of interest; (ii)&nbsp;a violation of criminal
law, unless he or she had reasonable cause to believe his or her conduct was lawful or no reasonable cause to believe his or her conduct
was unlawful; (iii)&nbsp;a transaction from which he or she derived an improper personal profit; or (iv)&nbsp;willful misconduct. Section&nbsp;180.0858(1)&nbsp;of
the WBCL provides that, subject to certain limitations, the mandatory indemnification provisions do not preclude any additional right
to indemnification or allowance of expenses that a director or officer may have under the Company&rsquo;s Articles of Incorporation, Bylaws,
a written agreement or a resolution of the Board of Directors or shareholders.</P>

that the termination of a proceeding by judgment, order, settlement, or conviction, or upon a plea of no contest or an equivalent plea,
does not, by itself, create a presumption that indemnification is not required. Section&nbsp;180.0853 of the WBCL permits the Company
to pay or reimburse reasonable expenses as incurred if the director or officer affirms his or her good faith belief that he or she has
not breached or failed to perform his or her duties to the corporation and undertakes to make repayment to the extent it is ultimately
determined that indemnification is not required.</P>

a federal or state statute, rule&nbsp;or regulation regulating the offer, sale or purchase of securities.</P>

with certain exceptions, a director is not liable to a corporation, its shareholders, or any person asserting rights on behalf of the
corporation or its shareholders, for damages, settlements, fees, fines, penalties or other monetary liabilities arising from a breach
of, or failure to perform, any duty resulting solely from his or her status as a director, unless the person asserting liability proves
that the breach or failure to perform constitutes any of the four exceptions to mandatory indemnification under Section&nbsp;180.0851(2)&nbsp;referred

accepted the improper distribution, as provided therein.</P>

which they are insured (subject to certain exceptions and limitations specified in the policy) against expenses and liabilities arising
out of proceedings to which they are parties by reason of being or having been directors or officers.</P>
