9. Dissolution. The Company shall be dissolved and its affairs shall be wound up (i) upon the decision by the Member to dissolve the Company, (ii) the bankruptcy of the Member, or (iii) any event causing a dissolution of the Company under the Act.

17. Liability of the Member. (a) Except as otherwise expressly provided in 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.

(b) No Indemnified Person (as defined below) shall be liable to the Company or the Member for any losses, claims, damages or liabilities arising from, related to, or in connection with this Agreement or the Company’s business or affairs (including any act or omission by any Indemnified Person), except for any losses, claims, damages or liabilities determined by final judgment of a court of competent jurisdiction to have resulted from such Indemnified Person’s gross negligence or wilful misconduct.

(c) The Company shall, to the fullest extent permitted by applicable law, indemnify and hold harmless each Indemnified Person against any losses, claims, damages or liabilities to which such Indemnified Person may become subject in connection with any matter arising from, related to, or in connection with this Agreement or the Company’s business or affairs, except for any such losses, claims, damages or liabilities determined by final judgment of a court of competent jurisdiction to have resulted from such Indemnified Person’s gross

negligence or wilful misconduct. If any Indemnified Person becomes involved in any capacity in any action, proceeding or investigation in connection with any matter arising from, related to, or in connection with this Agreement or the Company’s business or affairs, whether or not pending or threatened and whether or not any Indemnified Person is a party thereto, the Company will periodically reimburse such Indemnified Person for its legal and other expenses (including the cost of any investigation and preparation) incurred in connection therewith; provided that such Indemnified Person shall promptly repay to the Company the amount of any such reimbursed expenses paid to it to the extent that it shall be ultimately determined that such Indemnified Person is not entitled to be indemnified by the Company in connection with such action, proceeding or investigation as provided in the exception contained in the immediately preceding sentence. If for any reason (other than failure to meet the applicable indemnification standards) 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 loss, claim, damage or liability in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and such Indemnified Person on the other hand or, if such allocation is not permitted by applicable law, to reflect not only the relative benefits referred to above but also any other relevant equitable considerations.

(d) “Indemnified Person” means the Member of the Company and its affiliates.

(e) Notwithstanding anything else contained in this Agreement, the indemnity obligations of the Company under paragraph (c) above shall:

(ii) extend upon the same terms and conditions to the directors, committee members and officers of the Indemnified Party;

(iii) inure to the benefit of the successors, assigns, heirs and personal representatives of the Indemnified Party and any such persons; and

(f) This Section 17 shall survive any termination of this Agreement and the dissolution of the Company.

18. Benefits of Agreement. None of the provisions of this Agreement shall be for the benefit of or enforceable by any creditor of the Company or by any creditor of the Member; provided, however that Section 17 shall benefit Indemnified Persons.

19. Headings. The titles of Sections of this Agreement are for convenience of reference only and shall not define or limit any of the provisions of this Agreement.

20. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, all rights and remedies being governed by such laws without giving effect to conflicts of law principles of such State. This Agreement shall be construed in accordance with § 18-1101 of the Act.

21. Amendments. This Agreement may not be amended, except by a writing signed by the Member. Pending any replacement or amendment of this Agreement, it is intended that the provisions of the Act be controlling as to any matters not set forth in the Agreement.

22. Severability. Each provision of this Agreement shall be considered separable, and if for any reason any provision or provisions hereof are determined to be invalid and contrary to any existing or future law, such invalidity shall not impair the operation of or affect those portions of this Agreement which are valid.
