Section XII.4Accounting upon Dissolution and Termination.  Upon the distribution of the assets of the Company in accordance with the provisions of Section 12.5 hereof, the Liquidating Trustee shall cause the Company's accountants to make a full and proper accounting of the assets, liabilities and operations of the Company, as of and through the date on which such distribution occurs.

13



(i)First, all liabilities and obligations of the Company (including, without limitation, loans from the Member) shall be paid to creditors of the Company or provided for (whether by establishing reasonable reserves or otherwise as the Liquidating Trustee shall reasonably deem appropriate); and
(ii)Second, to the Member.
(b)The Liquidating Trustee shall have the authority to establish reasonable reserves for the payment of liabilities and obligations of the Company or to otherwise provide for the payment of Company liabilities and obligations as the Liquidating Trustee shall reasonably deem appropriate (as aforesaid).  All saleable assets of the Company may be sold in connection with the liquidation of the Company at public or private sale and at such price and upon such terms as the Liquidating Trustee, in its sole discretion, may deem advisable. The Member or any other Related Person may purchase assets at such sale. The Liquidating Trustee shall determine, in its sole discretion, which assets of the Company shall be liquidated through sale and which assets of the Company shall be distributed in kind.
Section XII.6Termination. Upon compliance with the foregoing distribution plan, the Company shall cease to be such, and the Liquidating Trustee shall execute, acknowledge and cause to be filed with the Secretary of State of the State of Indiana Articles of Dissolution of the Company.
