ARTICLE 6
Dissolution and Termination

6.1 Dissolution Events. The Company shall be dissolved and its business wound up:

(a) upon the determination of the Member that the Company should dissolve;

(b) upon the sale, exchange, forfeiture or other disposition of all or substantially all of the assets of the Company;

(d) upon the dissolution of the Member or any other event which terminates the continued membership of the Member or which results in the dissolution of the Company under the laws of the State of Delaware.

6.2 Distributions Upon Dissolution.

(a) Upon the dissolution of the Company, the Company's assets shall be disposed of and its affairs wound up. The Company shall give written notice of the commencement of the dissolution to all of its known creditors. The Member shall be furnished with an unaudited financial statement, prepared by the Company's independent accountants, setting forth the total amount of assets and liabilities of the Company as of the date of dissolution of the Company. During the period of the winding up of the Company, the affairs of the Company shall continue to the extent necessary to permit an orderly termination thereof. Following termination of the Company's business operations, to the extent that the Company's cash is insufficient to pay all of the liabilities of the Company to third parties all non-cash assets of the Company shall be offered, in their entirety or on an asset-by-asset basis, promptly for sale upon such terms as the Member may determine. The Member shall not be precluded from negotiating or bidding for the purchase of any or all of the assets offered for sale. If any such assets are not sold or the Member agrees to distribute such assets in kind, such assets shall be valued at their then fair market value.

(b) The Company's assets shall be used and distributed first to pay the liabilities of the Company to third parties including the expenses of liquidation. After payment of such liabilities, the Company shall set up such reserves as it deems reasonably necessary for any contingent or unforeseen liabilities of the Company, and for the maintenance of such insurance as it deems reasonably necessary for occurrences for which claims have not yet been made. The remaining Company assets shall then be applied in the following order: (a) to the repayment of any loans or advances made to the Company by the Member as creditor; (b) as a liquidating Distribution to the

Member. To the extent practicable, the Company assets, including any intellectual property rights, shall be distributed in kind to the Member.

ARTICLE 7
Miscellaneous

7.1 Full Integration. This Agreement shall not be amended, altered, changed or added to except in a writing executed by the Member.

7.2 Tax Classification. The Company intends to be disregarded as an entity separate from its owner (the Member) for U.S. federal, and to the extent permissible state and local, income tax purposes at all times. The Company and the Member agree to cooperate in all reasonable ways to ensure this result. If the Company is able to secure such classification by an election or filing with any tax authorities, the Member and the Company, as applicable, shall make or consent to the making of such election or filing.

7.3 Governing Law. This Agreement shall be governed by, and shall be construed in accordance with, the laws of the State of Delaware, without regard to the choice-of-law principles of the State of Delaware.
