          9. Exculpation and Indemnification. No Member or officer or other authorized agent of the Company shall be liable to the Company, or any other person or entity who has an interest in the Company, for any loss, damage or claim incurred by reason of any act or omission performed or omitted by such person in good faith on behalf of the Company and in a manner reasonably believed to be within the scope of the authority conferred on such person by this Agreement, except that such person shall be liable for any such loss, damage or claim incurred by reason of such person’s willful misfeasance or bad faith. In the event that the Member, or any of its direct or indirect members, partners, directors, managing directors,

officers, stockholders, employees, agents, affiliates or controlling persons, or any officer of the Company (collectively, the “Indemnified Persons”; and each an “Indemnified Person”), becomes involved, in any capacity, in any threatened, pending or completed, action, suit proceeding or investigation, in connection with any matter arising out of or relating to the Company’s business or affairs, to the fullest extent permitted by applicable law, any legal and other expenses (including the cost of any investigation and preparation) incurred by such Indemnified Person in connection therewith shall, from time to time, be advanced by the Company prior to the final disposition of such action, suit, proceeding or investigation upon receipt by the Company of an undertaking by or on behalf of the Indemnified Person to repay such amount if it shall ultimately be determined that such Indemnified Person is not entitled to be indemnified by the Company in connection with such action, suit proceeding or investigation as provided in the exception contained in the next succeeding sentence. To the fullest extent permitted by law, the Company also will indemnify and hold harmless an Indemnified Person against any losses, claims, damages, liabilities, obligations, penalties, actions, judgments, suits, proceedings, costs, expenses and disbursements of any kind or nature whatsoever (collectively, “Costs”), to which such an Indemnified Person may become subject in connection with any matter arising out of or in connection with the Company’s business or affairs, except to the extent that any such Costs result solely from the willful misfeasance or bad faith of such Indemnified Person. If for any reason (other than the willful misfeasance or bad faith of such Indemnified Person) the foregoing indemnification is unavailable to such Indemnified Person, or insufficient to hold it harmless, then the Company shall contribute to the amount paid or payable by such Indemnified Person as a result of such Costs in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand and such Indemnified Person on the other hand but also the relative fault of the Company and such Indemnified Person, as well as any relevant equitable considerations. The reimbursement, indemnity and contribution obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have to any Indemnified Person and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company and any Indemnified Person. The reimbursement, indemnity and contribution obligations of the Company under this Section shall be limited to the Company’s assets, and no Member shall have any personal liability on account thereof. The foregoing provisions shall survive any termination of this Agreement.

          10. Dissolution. The Company shall dissolve, and its affairs shall be wound up upon the first to occur of the following: (a) the written consent of the Member and (b) the entry of a decree of judicial dissolution under Wis. Stat. §183.0902.

          The bankruptcy of the Member shall not cause the Member to cease to be a member of the Company and upon the occurrence of such an event, the business of the Company shall continue without dissolution.

          In the event of dissolution, the Company shall conduct only such activities as are necessary to wind up its affairs (including the sale of the assets of the Company in an orderly manner), and the assets of the Company shall be applied in such manner, and in such order of priority, as determined by the Member, subject to any requirements of the Act.

          11. Treatment for Tax Purposes. It is the intention of the Member that the Company be treated as an entity disregarded from its owner for federal, state and local income tax purposes.

          12. Capital Contributions. Without creating any rights in favor of any third party, the Member may, from time to time, make contributions of cash or property to the capital of the Company, but shall have no obligation to do so.

          13. Distributions. Distributions shall be made to the Member at the times and in the aggregate amounts determined by the Member.

          14. Assignments. The Member may transfer or assign, in whole or in part, its limited liability company interest. Any assignee of the Member’s limited liability company interest shall only become a member of the Company upon the consent of the Member.

          15. Admission of Additional Members. One or more additional members of the Company may be admitted to the Company with the consent of the Member.

          16. Amendments. This Agreement may not be modified, altered, supplemented or amended except pursuant to a written agreement executed and delivered by the Member.

          17. Limited Liability. Except as otherwise provided by the Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and the Member shall not be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a member of the Company.

          18. No Third Party Beneficiaries. The right or obligation of the Member to call for any capital contribution or to make a capital contribution or otherwise to do, perform, satisfy or discharge any liability or obligation of the Member hereunder, or to pursue any other right or remedy hereunder or at law or in equity, shall not confer any right or claim upon or otherwise inure to the benefit of any creditor or other third party having dealings with the Company; it being understood and agreed that the provisions of this Agreement shall be solely for the benefit of, and may be enforced solely by, the Member and its successors and assigns except as may be otherwise agreed to by the Company in writing with the prior written approval of the Member.

          19. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED UNDER, THE LAWS OF THE STATE OF WISCONSIN, ALL RIGHTS AND REMEDIES BEING GOVERNED BY SAID LAWS, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS.
